Taking God at His Word

I see a rainbow during a summer shower, do I believe what God is saying? (Genesis 9:12-13). Do I believe that if I put Him first (keep Him as my focus), and keep His commands...that it will TRULY prolong my life in peace? (Proverbs 3:1). I look at my year-old, baby daughter...do I believe the Lord will "bless her and keep her", and that she (herself) is a gift from His hand (Numbers 6:24, James 1:17)? Do I take God at His Word?
