“Jesus said to him, ‘No one who puts his hand to the plow and looks back is fit for the kingdom of God.'” (Luke 9:62 ESV)

Practically, if you want to plow a straight furrow, you have to keep your eyes forward. Plowing requires forward focus. Following Jesus is similar. If you want to be His follower, you must keep your eyes on Him. Clinging to your past, you will lose sight of where Jesus leads. Following Jesus requires total surrender to His leading.
