1 Chronicles 28:20 records the charge that king David tell his son Solomon. He counsels his son to be strong and of good courage and to build (do) the temple of God according to the pattern God had written (1 Chronicles 28:19). He tells his son not to be afraid or to lose courage because he avers that God will be with Solomon and that God will not fail nor forsake Solomon until the work of God in building His temple is finished.

Our commission is to reconcile man to God so that their minds are renewed to not conform to the patterns of this world but to the pattern of Jesus Christ, God’s son. We are commissioned to build the temple of God i.e., reconcile man to God so that their bodies (which is the temple of the Living God) are presented as living sacrifices. Unfortunately, many times we are timid and fearful when it comes to acting on this commission. We can however take heart from the words of a king who said that God will not fail nor forsake until the work of building His temple (the people who come to his saving grace) is finished. And more importantly, we can take heart from the words of THE KING of kings, Jesus Christ, who said, “I will never leave (fail) you nor forsake you and lo I am with you even unto the ends of the world” (Hebrews 13:5-6; Matthew 28:20)

20 And David said to Solomon his son, Be strong and of good courage, and do it: fear not, nor be dismayed: for the LORD God, even my God, will be with thee; he will not fail thee, nor forsake thee, until thou hast finished all the work for the service of the house of the LORD.

Philippians 1:6 (KJV)
6 Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ:
