Paul explained that, through the sacrifice of Jesus, and the grace of God, all men can become the "sons of God" through "adoption":
"For as many as are led by the Spirit of God, they are the sons of God. " (Romans 8:14)
"For the earnest expectation of the creature waiteth for the manifestation of the sons of God." (Romans 8:19)
"And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty." (2Corinthians 6:18)
"To redeem them that were under the law, that we might receive the adoption of sons. And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father." (Galatians 4:5-6)
