🌾 Those who put confidence in the flesh are those who think they are not such bad people. The good they do puffs them up and fortifies the assumption that they are good people. On the other hand, Jesus and Paul both knew that no matter how much good they did, while in the flesh, it would not make them good people. That is why the good they did was to glorify the Father and not self. They lived to glorify the Spirit (which is God), not the flesh.
Think about this. Can you think of any other way of overcoming evil other than by doing good? If you did good to glorify self, would that not that be evil?
Instead of seeking your own good, the Lord wants you to seek the good of your neighbor, as a happy slave of Christ, doing the Will of God from the heart. If you empty yourself and take on the form of a servant as Christ did, you will have perfect peace and you will be giving that which is within as charity.
And Jesus said to him, "Why do you call Me good? No one is good except God alone."
Luke 18:19
Let no one seek his own good, but that of his neighbor.
1 Corinthians 10:24
It is not this way among you, but whoever wishes to become great among you shall be your servant, 27 and whoever wishes to be first among you shall be your slave; 28 just as the Son of Man did not come to be served, but to serve, and to give His life a ransom for many.
Matthew 20:26-28
