O give thanks unto the Lord ; for he is good; for his mercy endureth for ever. 1 Chronicles 16:34 KJV
Rejoice in His goodness and mercy. They are unending.
It is God’s goodness, His mercy and loving kindness, that is expressed by grace, and manifest in Christ Jesus.
It is also demonstrated by His unalterable covenants with Israel and His Church.
He is just and must exact the penalty of sin. He is bound by His righteous judgement.
In order to satisfy the law, He sent His Son, His only begotten Son, Jesus the Christ, to bear the penalty due the sin.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. John 3:16 KJV
