Psalms 89:15

Psalms 89:15 says, Blessed is the people that know the joyful sound: they shall walk, O LORD, in the light of thy countenance.  The joyful sound would be the voice of God calling the people to walk in His light I believe.  Verse sixteen adds, In thy name shall they rejoice all the day: and in thy righteousness shall they be exalted.  Those who hear and respond to God's call to salvation should rejoice all day so that God's name will be exalted.  Since we have everlasting life through our faith in Jesus Christ, there should be nothing in the world that keeps us from rejoicing.  Verse seventeen continues, For thou art the glory of their strength: and in thy favour our horn shall be exalted.  God is said to be the source of the strength of Isreal, and He is still the source of our strength as Christians today.  Verse eighteen concludes, For the LORD is our defence; and the Holy One of Israel is our king.  Just like the people of Israel then, God is still our defence as followers of Christ today and He is our eternal King.  Verse nineteen states, Then thou spakest in vision to thy holy one, and saidst, I have laid help upon one that is mighty; I have exalted one chosen out of the people.  This could have applied to David and the promises that God made to him, but in the overall view apply to Jesus Christ, Who is the true and only exalted One.  Verse twenty adds, I have found David my servant; with my holy oil have I anointed him:  David was indeed anointed as the king of Israel, God's chosen people, for a time, but Jesus Christ was anointed as the King of God's people for all time.  Verse twenty-one continues, With whom my hand shall be established: mine arm also shall strengthen him.  God was the source of David's power,  and He is the source of power for the followers of Christ today.  Verse twenty-two says, The enemy shall not exact upon him; nor the son of wickedness afflict him.  David at times did suffer defeat, but Jesus Christ never will, nor will we as Christians in the everlasting view.  Nothing can separate those who put their faith in Jesus Christ from everlasting victory over any enemy in the world.  Verse twenty-three continues, And I will beat down his foes before his face, and plague them that hate him.  The enemies of Christ have already been beaten down by His death on the cross and resurrection to everlasting life, and so have ours from a spiritual point of view if we have put our faith in Him.  Verse twenty-four states, But my faithfulness and my mercy shall be with him: and in my name shall his horn be exalted.  God's faithfulness will always be with His Son Jesus Christ, and with us if we have accepted Him as our Savior and Lord.  Verse twenty-five adds, I will set his hand also in the sea, and his right hand in the rivers.  God the Father gave Jesus Christ the Son power over everything.  I do not totally understand the Trinity, but I know that Father, Son and Holy Spirit are one God, not three.  Verse twenty-six continues, He shall cry unto me, Thou art my father, my God, and the rock of my salvation.  Verse twenty-seven concludes, Also I will make him my firstborn, higher than the kings of the earth.  As Christians, Jesus Christ, the only begotten Son of the heavenly Father, is our rock and salvation in the world today, and nothing can ever separate us from Him.
