James 1:5-8

5If any of you lacks wisdom, he should ask God, who gives generously to all without finding fault, and it will be given to him. 6But when he asks, he must believe and not doubt, because he who doubts is like a wave of the sea, blown and tossed by the wind. 7That man should not think he will receive anything from the Lord; 8he is a double-minded man, unstable in all he does.

Romans 12:1,2

1Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God-this is your spiritual act of worship. 2Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is-his good, pleasing and perfect will.
