Deuteronomy 31:13 - Their children must hear it read too. They don’t know this law yet. They too must learn to have respect for the Lord your God. They must honor him as long as you live in the land.This verse is absolutely true - our grandchildren must hear about God from us, so they will know Him. They need to “meet” Him, so they will learn to have respect for God and honor Him. For this to truly happen, they must see we respect and honor Him.
This is just one example, but no matter the age of our grandchildren, we need to be absolutely sure they hear about God, His Word, His great love for them, His amazing grace and how He answers prayer, so they will know Him. They absolutely need to see how we respect and honor God and experience both talking with God and seeing how He answers our prayers, because at the end of the day, we want them to grow to be people who know, respect and honor God.
