6 And now, my beloved son, notwithstanding their hardness, let us labor diligently; for if we should cease to labor, we should be brought under condemnation; for we have a labor to perform whilst in this tabernacle of clay, that we may conquer the enemy of all righteousness, and rest our souls in the kingdom of God.
We all have a labor to perform. If we work to conquer Satan in our own lives and help others to overcome his temptations, we will be free to rest our souls in the kingdom of God some day.
25 My son, be faithful in Christ; and may not the things which I have written grieve thee, to weigh thee down unto death; but may Christ lift thee up, and may his sufferings and death, and the showing his body unto our fathers, and his mercy and long-suffering, and the hope of his glory and of eternal life, rest in your mind forever.
26 And may the grace of God the Father, whose throne is high in the heavens, and our Lord Jesus Christ, who sitteth on the right hand of his power, until all things shall become subject unto him, be, and abide with you forever. Amen.
Wouldn't it be wonderful if the hope of glory and eternal life could "rest in your mind forever?"
