This song - The Words I Would Say, by Sidewalk Prophets - moves me to tears every single time. The chorus (especially toward the end) just says exactly what I want for my little girls to know, to always remember:
"Be strong in the Lord and never give up hope - you're going to do great things, I already know. God's got His hand on you, so don't live life in fear. Forgive and forget, but don't forget why you're here. Take your time and pray. Thank God for each day. His love will find a way. These are the words I would say..."
Listen to it for yourself HERE - it's a beautiful song.
