This verse is the greatest example of the true essence of the message of a disciple of Jesus Christ in all of the New Testament.
God’s first sovereign work of grace is summed up in the words, “. . . that they may receive forgiveness of sins . . . .” When a person fails in his personal Christian life, it is usually because he has never received anything. The only sign that a person is saved is that he has received something from Jesus Christ. Our job as workers for God is to open people’s eyes so that they may turn themselves from darkness to light. But that is not salvation; it is conversion-only the effort of an awakened human being.
