Psalms 89:28

Psalms 89:28 says, My mercy will I keep for him for evermore, and my covenant shall stand fast with him.  Jesus Christ is the source of salvation.  God's mercy is extended to sinners through Jesus Christ forevermore and God's covenant stands fast with Him.  Verse twenty-nine adds, His seed also will I make to endure for ever, and his throne as the days of heaven.  Matthew Henry says this could be seen as applying to David and his descendants until Jesus came, or to Jesus Himself.  If it is applied to Jesus, His seed would be those who put their faith in Him and not direct physical seed or descendants.  Verse thirty states, If his children forsake my law, and walk not in my judgments;  There is a warning to those who claim to be God's children but who do not obey His law, and even to those who are but fail to do so.  Being a Christian does not free us from following God's laws.  Verse thirty-one adds, If they break my statutes, and keep not my commandments;  Verse thirty-two continues, Then will I visit their transgression with the rod, and their iniquity with stripes.  If we, as followers of Christ, fail to keep God's laws, either by omission or commission, God will chastise us.  We cannot expect God to simply let us do whatever we want to do as Christians, even though we have everlasting salvation through our faith in Jesus Christ.  Verse thirty-three declares, Nevertheless my lovingkindness will I not utterly take from him, nor suffer my faithfulness to fail.  God said that even if those who have put their faith in Jesus Christ fail to keep His laws, He will not take His lovingkindness from them.  We have everlasting salvation through faith in Jesus Christ, and nothing can take that from us, because it is secured by God's mercy and righteousness and not ours.  Verse thirty-four adds, My covenant will I not break, nor alter the thing that is gone out of my lips.  We may break out covenant with God by failing to keep His laws, but He will never break His covenant with us, which promises us everlasting life through faith in Jesus Christ.   We cannot have salvation by faith in Jesus Christ alone and then lose it by our actions.  Verse thirty-five continues, Once have I sworn by my holiness that I will not lie unto David.  This speaks of the covenant relationship between David and God, which culminated with Jesus Christ, a physical descendant of David.  God's covenant is secured by His holiness, and not by David's then nor ours now.  Verse thirty-six says, His seed shall endure for ever, and his throne as the sun before me.  David's descendant, Jesus Christ, is the One through Whom this promise is fulfilled.  It does not mean that we must be a physical descendant of David to have a covenant relationship with Him, but that we must be a spiritual descendant through our relationship with Jesus Christ.  Verse thirty-seven adds, It shall be established for ever as the moon, and as a faithful witness in heaven. Selah.  God's relationship with those who enter into a covenant relationship with Him through faith in Jesus Christ is everlasting.
