Psalm 105:45 That they might observe his statutes, and keep his laws. Praise ye the Lord.
The Lord has delivered His people, brought them forth with joy, and gave them the lands of the heathen. God’s great Exodus and Conquest was accomplished by Him alone with the purpose that the redeemed people might keep their part of the covenant according to His laws. God’s Redemption has a purpose: that they would worship God and lives of love for God and one another. Ephesians 2:10: “We are created in Christ Jesus for good works…that we should walk in them.”
The purpose and result of Christ’s work of salvation and new life is that by the power of the Spirit we would actually live lives of love according to the covenant commandments, do the good works of loving God and one another. A life of keeping is our response to the Gospel. Our lives become lives of praise for the goodness and greatness of God for loving us first.
When we believe and receive His covenant love we gladly respond with covenant love for God and people. We study the Law to know what to do; we hear and believe the Gospel to have the desire and ability to keep.
