True, Absolute Power
Psalms 110:1 The LORD said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool.
"THE SON OF GOD BECAME A MAN TO ENABLE MEN TO BECOME SONS OF GOD". - C.S. LEWIS
I believe David was a shadow, a type of Christ Jesus ( Note 1) for the purpose of giving us a vivid example of Jesus. One of the many examples given by David's life as a type of Christ was how the enemy came against him to destroy him and how he overcame by constant communion with the Father. Psalms 22:1: sets the scene for the ultimate pain in crucifixion which is God turning His back on His own son, bearing all the sins of the world.
."Oh God I pray that I may know through the Holy Spirit the immeasurable power of God through Jesus Christ my Lord for your glory and purpose, amen...
Note 1: a type in scripture is a person or thing in the Old Testament which foreshadows a person or thing in the New Testament. For example, the flood of Noah’s day (Genesis 6-7) is used as a type of baptism in 1 Peter 3:20-21. The word for type that Peter uses is figure.
When we say that someone is a type of Christ, we are saying that a person in the Old Testament behaves in a way that corresponds to Jesus’ character or actions in the New Testament. When we say that something is “typical” of Christ, we are saying that an object or event in the Old Testament can be viewed as representative of some quality of Jesus.

The Lord anointed David with the holy oil, not only as an emblem of the graces and gifts he received, but as a type of Christ, the King Priest, and Prophet, anointed with the Holy Ghost without measure. David after his anointing, was persecuted, but none could gain advantage against him. Yet all this was a faint shadow of the Redeemer's sufferings, deliverance, glory, and authority, in whom alone these predictions and promises are fully brought to pass. source: Matthew Henry commentary on Psalms 89)
The psalm is a prayer, a solemn address to God, at a time when the psalmist was brought into distress by the malice of his enemies. Many such times passed over David, nay, there was scarcely any time of his life to which this psalm may not be accommodated, for in this he was a type of Christ, that he was continually beset with enemies, and his powerful and prevalent appeals to God, when he was so beset, pointed at Christ's dependence on his Father and triumphs over the powers of darkness in the midst of his sufferings. In this psalm, I. David settles a correspondence between his soul and God, promising to pray, and promising himself that God would certainly hear him (v. 1-3). II. He gives to God the glory, and takes to himself the comfort, of God's holiness (v. 4-6). III. He declares his resolution to keep close to the public worship of God (v. 7). IV. He prayed, 1. For himself, that God would guide him, (v. 8). 2. Against his enemies, that God would destroy them (v. 9, 10). 3. For all the people of God, that God would give them joy, and keep them safe.
