John 3:21

To 'do the truth,' means to live the Christian life, for Christian truth is more than a belief, it is a way of life. The phrase is peculiar to St. John: cp. 1 John 1:6.

22-36. Jesus leaves Jerusalem and baptises in the country districts of Judæa, where He probably spent most of the time from the Passover, 27 a.d., to the late harvest (December) of the same year: see on John 4:35. His great success rouses the jealousy of John's disciples (John 3:26), but the Baptist, so far from regarding Christ's disciples as too many, laments that they are too few (John 3:32), and again testifies his belief in Christ's Messiahship.
