God not only made us, but in the perfect creation He also sustains us. Something bad happened. Because we are separated from God by our sin, we begin to die the moment we sin. We are separated from our source and sustenance of life. ‘Wages’ implies a just and deserving outcome to our sin.
Because we are separated from God, we are separated from life, peace and joy.
But there is good news.
That separation that caused death was overcome when Christ took on human flesh and died for us, uniting us with God. ‘Gift’ means undeserved. We sinned and deserved to die, but God, at great cost, has given us THE free gift of eternal life, through Jesus Christ our Lord.
