In the Lives of Christians (John 14:14)

If the Son of God needed to pray, how much more do we? Jesus said that we “ought to pray and not lose heart” (Luke 18:1). He told us to ask, seek, and knock (Matthew 7:7–8). And He warned that the spirit of man is willing, but the flesh of man is weak (Matthew 26:41). Prayer is where the real battle of the spiritual life exists, and the flesh would rather do anything except pray. In our casual, energetic culture, we have learned to pray while we jog, work out, or take walks for exercise. And that’s fine. But Jesus found it necessary to get away and do nothing but pray—probably the kind of example we should follow.
