That's the most precious gift: Real love, God's Love, His Love in a little child--so sweet and beautiful!--Blessed of the Lord before birth and given of God to His children for His service. They're His children and He wants us to take care of them and train them! Like flowers in your garden, they're a gift of God, but you've got to take care of them! God's gifts are God's work!
If we "train up the children in the way they should go, when they are old they will not depart from it." (Pro.22:6) They will very likely do a bigger job for God than you have done or ever will do, if you will only teach, train and lead them right, set the right example, and launch them into service for the Lord. "And all thy children shall be taught of the Lord; and great shall be the peace of thy children!" (Isa.54:13)
Another wonderful thing about our children is that we're going to have them forever! Little new created souls, they are going to be with us always!--And if you've reared them right and done a good job of God's work with God's gift, you're going to be so thankful when you get to Heaven!
