Our reward for obedience and our relationship with God does not come in this lifetime. Our reward comes in heaven. In Matthew 6:19-20 Jesus said, 19 Do not store up for yourself treasures on earth, where moth and rust destroy, and where thieves break in and steal. 20 But store up for yourselves treasures in heaven, where moth and rust do not destroy, and where thieves do not break in and steal. When we worry about the things of this life we hold ourselves back from looking forward to our true reward in heaven and we limit our effectiveness for the glory of God.
