Nothing complicated, we are either with God or against God. With God, we can experience many blessings – a great life. Against God, we will experience discipline, again and again until we realize our sin and repent. Note that this was written for God’s children. Those of us who, when we cried out to Him, He saved from slavery and despair.
The difference between being with God and against God is great. Don’t be stubborn, choose God.
