Speaking God’s Word Over Children via Priscilla Shirer
You are a man of integrity and character. You will love the Lord your God with all your heart, all your soul and all your strength. You will be a blessing to your teachers and a blessing to your friends. You are the head and not the tail. You are above and not beneath. You are a leader and not a follower. After that, I normally say only a few more things before the day begins. . . You are the temple of the Holy Spirit. You are a man of valor. You have the whole armour of God so that you can stand against the schemes of the devil. You will bless the Lord at all times and His praises shall continually be in your mouth. source: Priscilla Shirer Blog
