Not by might nor by power, but His Spirit. The true definition of a successful life is living the life that God has destined for us by His might and power which is the Holy Spirit. Realizing that what God has for me need not my strength but for me to willing surrender to him by denying and emptying myself so that His ability and power can be reveled through me without any hindrances. Also, what Pastor said in the beginning about having a hunger for the Lord I think is the key to all of this because it is the determining factor to the amount we receive from God. Although we might say we want the things of God, if its not followed up by action (which true hunger will cause some sort of action ) then its just a mere wish.
