To intercede is to stand before God on behalf of someone else. It is the friend who prays a struggling marriage through the night, the mother who has carried a wandering child to God for twenty years, the small group that lifts a sick name week after week. Intercessory prayer is one of the most ordinary things Christians do — and one of the most mysterious, because in it God invites us to have a real part in what he does in other people’s lives.

Here is what intercessory prayer is, why it matters more than we tend to think, and how to actually do it.

A ministry we are all called to

Scripture treats intercession not as an advanced spiritual specialism but as a basic Christian duty and privilege. Paul opens his instructions on prayer with it: “First of all, then, I urge that supplications, prayers, intercessions, and thanksgivings be made for all people” (1 Timothy 2:1). And he tells the Ephesians to keep “praying at all times in the Spirit, with all prayer and supplication. To that end keep alert with all perseverance, making supplication for all the saints” (Ephesians 6:18).

The old prophet Samuel went so far as to call the failure to intercede a sin: “Far be it from me that I should sin against the Lord by ceasing to pray for you” (1 Samuel 12:23). To pray for others, on this view, is not a favor we do God or them; it is part of what it means to love our neighbor before the throne of grace.

Why it actually matters

Does intercession change anything, or only comfort the one praying? Scripture is bold here: “The prayer of a righteous person has great power as it is working” (James 5:16). God, in his wisdom, has chosen to make the prayers of his people one of the ordinary means by which he acts in the world. This does not put us in control — God remains God — but it means our praying is not a formality. It is a genuine instrument in his hands.

E. M. Bounds, who wrote more searchingly on prayer than almost anyone, argued in Purpose in Prayer that God’s great works have always followed the persistent praying of his people — that intercession is not merely the preparation for the work; it is the work, the pipeline through which heaven’s power reaches earth.

This raises an old question: if God already knows what people need and is good, why should our asking change anything? The Bible never fully unties that knot, but it is emphatic on the fact: God has chosen to work in response to prayer. “You do not have, because you do not ask” (James 4:2). He is a Father who delights to give, and who has arranged his world so that the prayers of his children are a real part of how he gives. This does not make us the source of the power — God is — but it makes us genuine participants. When you intercede, you are not informing God of something he missed, nor bending a reluctant hand. You are joining him in what he loves to do, and taking up the astonishing dignity he has given ordinary people: to ask, and to see him act.

We do not intercede alone

Intercession can feel daunting — we often do not even know what to ask. Here Scripture offers enormous comfort: we are not left to it by ourselves. “The Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words” (Romans 8:26–27). When your words run out, the Spirit’s do not.

And above even that, we have an Intercessor in heaven itself. Christ “always lives to make intercession” for those who come to God through him (Hebrews 7:25). Your prayers for others do not ascend alone; they join the ceaseless prayer of the risen Son, who told Peter, “I have prayed for you that your faith may not fail” (Luke 22:32). When you intercede, you are doing on earth what Jesus is doing in heaven — and in his name your small prayers are carried.

Praying for those who don't yet believe

Some of the most persistent intercession in Christian history has been for people who were, at the time, far from God. Paul’s “heart’s desire and prayer to God” was for the salvation of his own people (Romans 10:1). Augustine of Hippo — one of the towering minds of the early church — was, for years, a wanderer his mother Monica would not stop praying for. She wept and interceded through his rebellion and his false turns, and by her own son’s later account it was those prayers, more than any argument, that God used to bring him home. George Müller prayed for the conversion of two friends for over fifty years; one came to faith shortly before Müller died, the other soon after — neither prayer wasted, though one outlasted the man who prayed it.

If you carry a wandering child, a hardened spouse, an indifferent friend, this is your encouragement: keep praying. You are not shouting into an empty sky. You are asking the God who gives new hearts (Ezekiel 36:26) to do the one thing you cannot do from the outside — reach the inside. No one is beyond the range of a mother’s, a friend’s, a stranger’s intercession, because no one is beyond the reach of the God it is addressed to.

How to actually do it

Andrew Murray called intercession The Ministry of Intercession precisely because he wanted ordinary believers to take it up as real, deliberate work rather than a vague good intention. A few practical patterns, drawn from Scripture and the great intercessors:

  • Pray specifically. Not “bless them,” but the actual need — the healing, the job, the softened heart, the salvation. A specific prayer can have a specific, recognisable answer.
  • Pray Scripture back to God. Paul’s prayers for the churches (Ephesians 1 and 3, Colossians 1) are a school of intercession — pray them, filling in the names of the people you carry.
  • Pray persistently. Epaphras is remembered as “always struggling on your behalf in his prayers” (Colossians 4:12). Intercession is often a long labor, not a single request. Do not stop because the answer is slow.
  • Pray with argument and expectation. Spurgeon, in his sermon Order and Argument in Prayer, noticed that the great pray-ers of Scripture reasoned with God, pleaded his promises, and expected him to answer. Come boldly.

When the answer is slow

The hardest thing about intercession is not starting but continuing — praying for the same person, the same situation, month after month, with no visible change. Here Jesus is remarkably direct. He told a parable, Luke says, “to the effect that they ought always to pray and not lose heart” (Luke 18:1) — the story of a widow who wore down an unjust judge by sheer persistence. His point is not that God is reluctant like that judge, but the opposite: if even a corrupt official yields to persistence, how much more will a good Father answer his children who cry to him day and night?

Delay, in Scripture, is almost never denial. It is the soil in which faith deepens and the heart is purified of wanting the gift more than the Giver. So when the answer is slow, do not conclude that your prayer failed or that God did not hear. The great intercessors treated a long silence not as a closed door but as a call to keep knocking. Some of the answers you are praying toward will come after years; some, like Müller’s, may come after you are gone. None is lost. God keeps every prayer, and he is never late, though he is often slower than our anxiety would like.

The widest circle

Jesus, on the night before he died, did not only pray for the friends in the room. He prayed “also for those who will believe in me through their word” (John 17:20) — which is to say, he prayed for you, by name-in-advance, two thousand years ago. That is the pattern intercession follows: love that reaches beyond the people in front of us to those we may never meet.

You do not need to be eloquent, gifted, or advanced to intercede. You need only to love people enough to carry them to God, and to keep carrying them. Begin small and concrete: a short list of names, prayed over each morning; a friend’s crisis held before God through the week; a wanderer refused to God’s mercy no more. You will rarely see the whole of what your prayers accomplish this side of eternity — but you will one day, and the sight will astonish you. In a world of problems too big for us to fix, intercession is the most powerful thing most of us will ever do for the people we love — because it puts them in the hands of the One who can.
