If you don't believe the love of God, you won't have confidence in Him to help you when you need it. You won't have confidence in Him to see you through hard days or difficult situations. Because God is love, He wants only the best for us. We usually apply these verses to ourselves, using them as a standard by which we can compare our behavior and check our love walk. Since God is love, then He must be perfect and complete in loving us in the way described in these verses.
Love never fails.
And since God is love, that means He will never fail you. I know mine does. The truth is, God wants to see you just as blessed as you can be. He wants His people to be in high places. He wants to promote us because we are His family and He loves us.
