Why did Jesus pray early in the morning (Mk.1:35)?
Because this is how He stayed engaged with the Father and the purpose He had for Him.
Well if that's what it took to empower Jesus to stay on task -- as the Son of God -- we must require it all the more.
Once the day gets going, all kinds of forces will array themselves against you... to lead you away from the purpose God has for you.
But praying early in the morning sets you up to overcome.
The battle is usually won -- or lost -- early.
