Consider Psalm 119, which is written from the aspect of someone who is attempting to grow in his relationship with the Lord. Verse 9 asks, “[How] shall a young man cleanse his way?” It answers, “By taking heed thereto according to thy word.” The disciples asked Jesus what they must do to work the works of God. He answered, “This is the work of God, that ye believe on him whom he hath sent” (John:6:28–29). In other words, our task is simply to believe, to take our first baby steps, and to let God take care of the rest.
"Believe on the Lord Jesus Christ, and thou shalt be saved."
