The Bible records the life of King David. The Bible mentions a very close relationship between God and David as it describes David as being a man after God’s own heart.
God also gave to David a divine and eternal promise delivered through Nathan the prophet known as the Davidic Covenant. This was an unconditional covenant through which God promised to David and Israel that the Messiah (Jesus) would come from the lineage of David and would establish a kingdom that would endure forever.
At the end of David’s life his son Solomon was designated by God as the replacement for David. The first in the long lineage of David leading to the Messiah. In 1 Chronicles 28 David gives to Solomon a blueprint for successful leadership both personally and nationally as king and urged him to embrace the blueprint. That blueprint has not changed and remains the blueprint for any and all people wanting to live or lead successfully today.
