Our only hope in this world is knowing we belong to God. If we were on our own, the weight and struggles of this life would crush us. The pressure would annihilate us. But thanks be to God, we are not alone. We are not our own. The life we live, we live because of Jesus and for Jesus.
Paul reminds us in Romans 14:7-8 that whether we live or die, we belong to the Lord. Our purpose for living is to do the work of our Lord. And when we die, we die for Him, having run the race and doing all He has given us to do (2 Timothy 4:7-8). This is our hope: we belong to the Lord.
