Psalm 22:30 Posterity will serve him; future generations will be told about the Lord.
Sometimes we may think that there is nobody else trying to make sure that the gospel gets told to the next generation, but God has promised us that His story will never go untold.
No matter how much we turn our back on Him, He will always make sure that there is someone else ready to tell others about Christ!
God has been faithful to this promise from the beginning of time and will continue with this promise until it is time for us all to go back with Christ! Never give up telling someone else about God!
