As a Christian, we must be constantly reminded that the purpose of our life is not to be successful in our career, not to be a good friend, not even a good parent or a good spouse.
No, those are all good to have but those are not the purpose of our life.
The purpose of our life is to glorify the Lord who died for our sin on the cross so we can be saved.
The purpose of our life is to bear the witness of His saving blood so to bring the good news to the lost souls.
That I shall always remember.
