Do not place your trust in yourself.

Proverbs 28:25-26

25 A greedy man stirs up dissension, but he who trusts in the LORD will prosper.

26 He who trusts in himself is a fool, but he who walks in wisdom is kept safe.

Proverbs 3:5-6

5 Trust in the LORD with all your heart and lean not on your own understanding;

6 in all your ways acknowledge him, and he will make your paths straight.

Luke 18:9-14

9 To some who were confident of their own righteousness and looked down on everybody else, Jesus told this parable:

10 “Two men went up to the temple to pray, one a Pharisee and the other a tax collector.

11 The Pharisee stood up and prayed about himself: ‘God, I thank you that I am not like other men—robbers, evildoers, adulterers—or even like this tax collector.

12 I fast twice a week and give a tenth of all I get.’

13 “But the tax collector stood at a distance. He would not even look up to heaven, but beat his breast and said, ‘God, have mercy on me, a sinner.’

14 “I tell you that this man, rather than the other, went home justified before God. For everyone who exalts himself will be humbled, and he who humbles himself will be exalted.”

2 Corinthians 1:9

Indeed, in our hearts we felt the sentence of death. But this happened that we might not rely on ourselves but on God, who raises the dead.
