Summary: If you are spiritually lost or unsure of salvation, today you can become a son of God by redemption and regeneration in Christ Jesus. You have to believe that he died in your place to pay your sins.

Intro: There are those that believe in the so-called “universal Fatherhood of God” and the “universal brotherhood of men.” However, the Holy Bible makes it very clear that, spiritually speaking, there are two fathers: God and Satan (see I John 3:10). Today, we shall talk about our spiritual sonship.
