‘Now the days of David drew near that he should die, and he charged Solomon his son, saying: “I go the way of all the earth; be strong, therefore, and prove yourself a man.”‘ (1 Kings 2:1-2 NKJV).

David’s last words to his son, Solomon, sound somewhat generic: “Be strong and prove yourself a man.” Yet, the verses that follow show that what he meant was that Solomon should “be strong” in the Lord and in His promises. And what he meant by “prove yourself a man,” was not about being macho, but about keeping the charge of the Lord and always walking in His ways.
David understood strength and manhood differently than the world. He wanted his son, Solomon, to be strong in the Lord and to walk as God’s man in all His ways. Yet, Solomon would not prove to be the man that David had hoped for, turning away to worship false gods as he grew older.
But God did not forget His promise that David would not “lack a man on Israel’s throne.” He sent His only Son, Jesus, to be born into the line of David, and to establish His eternal kingdom. Jesus was strong in the Lord and proved Himself the Son of Man, who takes away the sins of the world.
As Pilate said, “Behold the man!” (John 19:5).
