Jesus cautioned us to not get arrogant about serving God!
Luke 18 ~
9 Then Jesus told this story to some who had great confidence in their own righteousness and scorned everyone else: 10 “Two men went to the Temple to pray. One was a Pharisee, and the other was a despised tax collector.11 The Pharisee stood by himself and prayed this prayer[a]: ‘I thank you, God, that I am not like other people—cheaters, sinners, adulterers. I’m certainly not like that tax collector! 12 I fast twice a week, and I give you a tenth of my income.’
13 “But the tax collector stood at a distance and dared not even lift his eyes to heaven as he prayed. Instead, he beat his chest in sorrow, saying, ‘O God, be merciful to me, for I am a sinner.’ 14 I tell you, this sinner, not the Pharisee, returned home justified before God. For those who exalt themselves will be humbled, and those who humble themselves will be exalted.”
