For I say, through the grace given to me, to everyone who is among you, not to think of himself more highly than he ought to think, but to think soberly, as God has dealt to each one a measure of faith. Romans 12:3 (nkj)
This means to me that when you realize you do have a measure of faith that God has placed in you, and you start to live a victorious life [being able to see the goodness of God in your life] we are not to obtain a high-minded way of thinking of ourselves. God gave us the faith, God provided His blessings in our lives, and God can take it all away. Final thought: God is no respecter of persons and if the person next to you displays his faith, he will see the same results that you saw displaying your faith.
