How has God sustained you throughout your life? How has He answered your prayers? How has He showed His love to you? Share these things with your grandchildren. When they are able to hear and see how God has sustained you, they will be better able to believe He will do the same for them and will know what it looks like when He does!
Help your family see and remember how God works in your lives. Do not forget. Remember and trust . . . how God is always faithful and will give us what we need to do what He asks us to do!
