We're called to be humble, not proud. Cultivate humility in your life, ministry, marriages, relationships. Daily keep going back to your saviour. Recognise you are a sinner saved by grace. Call yourself a servant: just a slave of God. Your life is not your alone, you are called by the Lord Jesus.
Don't compare youself with other people, but you're thankful for God's work in their life, and you're not jealous. You look for signs of grace in others and other churches.
Pride is something the devil takes hold of and it can destroy your ministry.
If God chooses to use you to grow his church, all glory to him. If he uses others, all glory to him.
