Read Colossians 4:1-18 personalizing these verses in prayer for your children.
V 2 Father, help my children to devote themselves to prayer, being watchful and thankful.
V 5 Help my children to be wise in the way they act toward outsiders, help them make the most of every opportunity (to further the Gospel and win others to you!)
V 6 Let their conversations be always full of grace, seasoned with salt, so that they may know how to answer everyone.
V 12 Father, please help my children to stand firm in all the will of God, mature and fully assured.
