Galatians 6

7 Do not be deceived: God is not to be mocked. Whatever a man sows, he will reap in return. 8 The one who sows to please his flesh, from the flesh will reap destruction; but the one who sows to please the Spirit, from the Spirit will reap eternal life.

2 Corinthians 11

12 But I will keep on doing what I am doing, in order to undercut those who want an opportunity to be regarded as our equals in the things of which they boast. 13 For such men are false apostles, deceitful workers, masquerading as apostles of Christ. 14 And no wonder, for Satan himself masquerades as an angel of light. 15 It is not surprising, then, if his servants masquerade as servants of righteousness. Their end will correspond to their actions
