We should keep our hearts and your minds pure. If a bad thought comes up, immediately cast it down. Don’t give room for the devil, if you do, he’ll want to control the whole house.
24 Put away from you crooked speech,
and put devious talk far from you.
25 Let your eyes look directly forward,
and your gaze be straight before you.
26 Ponder[a] the path of your feet;
then all your ways will be sure.
27 Do not swerve to the right or to the left;
turn your foot away from evil.
2 Corinthians 10:4-5
4 The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. 5 We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ.
