Expositor's Bible Commentary Commentary Mark 11:25

"And whensoever ye stand praying, forgive, if ye have aught against any one; that your Father also who is in heaven may forgive you your trespasses." — Mark 11:25 (ASV)

The transition between v.24 and v.25 is abrupt, but there is a connection. To be effective prayer must be offered in faith—faith in the all-powerful God who works miracles. But it must be offered in the spirit of forgiveness. Faith and the willingness to forgive are the two conditions of efficacious prayer.
