Pride consists of self-interest which fights to keep its position. If pride exists in the church, it creates a pecking order that cripples God's people. Pride will also block God from answering prayer. So what is the deathblow to pride?
Pride cannot survive where self-sacrificing love exists. The example of Jesus Christ teaches us what that love looks like. It includes putting others above yourself. Also, it means to make yourself of no reputation–even to the point of death.
If you're walking in pride today, the remedy is to confess and repent to God. Then, by the grace of God, let the Holy Spirit fill your heart with the self-sacrificing love of Jesus!
