Contradiction with John 10:10
Luke 3:20 discusses Herod imprisoning John, which contradicts John 10:10 about Jesus bringing abundant life, contrasting the oppression and limitation of imprisonment.
John 10:10: The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have [it] more abundantly.
Contradiction with Galatians 5:1
Luke 3:20 describes imprisonment, while Galatians 5:1 speaks of standing firm in the freedom Christ provides, opposing the confinement seen in Luke.
Galatians 5:1: Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.
