Sometimes, all it takes is remembering—remembering what the Lord has done for us in spite of ourselves.
I can't get over how blessed I am. I am such a failure at life, but God doesn't cease showering me with His blessings. Whenever you find yourself in a complaining or mopey mood, just sit back and remember and recognize that He remembered you first.
"The LORD has remembered us; He will bless us." Psalm 115:12
