English Standard Version
25And whenever you stand praying, forgive, if you have anything against anyone, so that your Father also who is in heaven may forgive you your trespasses."Some manuscripts add verse 26: But if you do not forgive, neither will your Father who is in heaven forgive your trespasses
25 And when you assume the posture of prayer, remember that it's not all asking. If you have anything against someone, forgive - only then will your heavenly Father be inclined to also wipe your slate clean of sins."
New King James Version
25 "And whenever you stand praying, if you have anything against anyone, forgive him, that your Father in heaven may also forgive you your trespasses.
New Living Translation
25 But when you are praying, first forgive anyone you are holding a grudge against, so that your Father in heaven will forgive your sins, too. "
The disciples could not think why that fig-tree should so soon wither away; but all wither who reject Christ; it represented the state of the Jewish church. We should rest in no religion that does not make us fruitful in good works. Christ taught them from hence to pray in faith. It may be applied to that mighty faith with which all true Christians are endued, and which does wonders in spiritual things. It justifies us, and so removes mountains of guilt, never to rise up in judgment against us. It purifies the heart, and so removes mountains of corruption, and makes them plain before the grace of God. One great errand to the throne of grace is to pray for the pardon of our sins; and care about this ought to be our daily concern.
