I was very despairing for my young grandchildren a while back. My son and his wife are not raising them to be Christians, even though they were both raised to be! We don't live in the same city, and only see them about once every two months. I pray for them all daily of course, but it was killing me to see them not getting any Bible training.
Well, a few years later, they are 4 and 3, and we have been praying with them at night and meals, and we take them to a near by church, where I know a lot of the people. They sit for the song service, and then go and get Bible stories and some work sheets to take home.
Yesterday, they sat quietly for the whole song service. They enjoyed their Sunday School class, and the 3 year old had me reading more Bible studies at night. He is quite taken by the OT stories of King David. When I pray, they know to fold their hands and bow their heads without me saying anything, and they say "amen" at the end.
I know it is a ways from being saved, but it shows that grandparents can have influence on their spiritual journey of their grandchildren. I know my grandmother always read me Bible stories and prayed with me. However, she forced my parents to send me to Sunday School, even though it was on my own. I was worried about them not getting the memory verses and stories I did, by attending church throughout the year, and even singing in the children's choir.
God is faithful with our children and grandchildren! We do need to train them up, but God can work miracles even when the reinforcement is not always there. My son recently told me he has started believing in Jesus again, but he is just not into church - yet, I say!
Thank God for the little children!
