He always stands by his covenant—
the commitment he made to a thousand generations.
Psalm 105:8 NLT
This verse describes God’s faithfulness in the covenant He made to His people, the Jews. It’s a covenant He is going to keep. What was it? A covenant is a binding agreement made between two parties. And in Genesis 17 we read, “.. This is the everlasting covenant: I will always be your God and the God of your descendants after you“. He will not try and wriggle His way out of it, when the going gets tough, as humans might do. But the covenantal agreement between God and His people was in two parts. God promised for His part to be always with them. And for their part they had to be obedient to Him and His laws, with a regime of sacrifices to atone for their sins. And as far as God was concerned His promise was eternal. Sadly, we see from the Old Testament the constant struggle the Jewish nation had in keeping their part of the agreement.
Through Jesus, God brought about a New Covenant. This New Covenant was mentioned by Jeremiah – he could see, through the inspiration of the Holy Spirit, a time coming when God would initiate a New Covenant. We read in Jeremiah 31:33, “But this is the new covenant I will make with the people of Israel after those days,” says the Lord. “I will put my instructions deep within them, and I will write them on their hearts. I will be their God, and they will be my people.” In Hebrews 7:22, we read, “…Jesus is the one who guarantees this better covenant with God“. In the New Covenant, God offered the free gift of forgiveness for our sins through Jesus’ sacrificial death at Calvary, and our responsibility is to have faith in what He did for us, in the process enjoying an eternal relationship with God.
But will God’s commitment come to an end? In today’s verse the Psalmist points out that God has limited His covenant to a thousand generations. It doesn’t seem so much until we realise that the genealogies in the Bible add up to around one hundred generations from Adam until today. So a thousand generations is as good as eternity.
But the important point of the Covenant is that God is a real, loving, Heavenly Father, His Son Jesus died to redeem us from the consequences of our sins, and we have an invitation to spend eternity with Him. Seems a good deal to me.
