We are warned to “cleanse ourselves” if we want to succeed in spiritual things.
When we do any work for the Lord it should be with one objective only, “that God be praised.”
To be successful in Christ, we must do whatever we do for the intent of glorifying Him.
1 John 1:9 If we confess our sins, he will forgive our sins, because we can trust God to do what is right. He will cleanse us from all the wrongs we have done.
