Verse explainer
A promise about prayer — but the phrase 'according to his will' is doing more work than most readers give it credit for.
And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:
BSBAnd this is the confidence that we have before Him: If we ask anything according to His will, He hears us.
The plain meaning
John is writing to believers who already know they have eternal life (v. 13) — and from that security he draws a further assurance: you can come to God with boldness, not timidity. The Greek word behind 'confidence' (parresia) literally means freedom of speech, the liberty a child has to speak openly to a parent. But the promise is not a blank check. The condition 'according to his will' is not a loophole John slipped in to protect God from awkward requests. It is the actual architecture of the promise — what makes it a real promise rather than a vending-machine formula. God's revealed will, expressed through Scripture and his covenant promises, is precisely what we are invited to pray into. The assurance is not that God performs whatever we name, but that when our asking is shaped by what he has already declared good, our prayers are genuinely received — heard, not merely tolerated. Verse 15 presses the point: if we know he hears us, we can know we have the petitions we asked. The confidence is grounded in relationship and alignment, not in the volume or cleverness of the request.
The common misreading
What the commentators say
Clarke reads 'according to his will' as meaning what God has already promised in his revealed word — not his hidden decrees, but his declared covenant mercies. On Clarke's reading, the condition is not a restriction that weakens the promise but a guide that sharpens it: find what God has promised, pray for that, and the ground is solid. Prayer that wanders outside the revealed will has no such footing.
Gill distinguishes God's secret will (his eternal purposes, unknown to us) from his revealed will (the covenant of grace, the promises laid up in Christ). It is the revealed will that governs prayer. When believers ask for grace, spiritual supply, or any mercy that God has openly promised in Christ, they are asking according to that revealed will — and Gill insists such askers will be heard and answered, though in God's time and way, not necessarily the petitioner's.
JFB observe that 'according to his will' is not experienced by the genuine believer as an external constraint but as the very content of faith-shaped desire. When we are fully abiding in God, our will and his converge — and prayer becomes the natural expression of that alignment. Where our will diverges from his, it is our wanting that is disordered, not God's hearing that is withheld.
The word behind it
'Confidence' or 'boldness.' The word originally meant the freedom of speech a citizen had in public assembly — the right to speak openly without fear. In the New Testament it carries the warmth of a child addressing a father directly, without shame or hesitation. It is the same word used in 1 John 4:17 for boldness on the day of judgment. Knowing this word changes the tone of the verse: John is not describing cautious petition but free, unhurried access.
