“Becoming joint heirs means that we become eternal children of God, as Jesus is the Son of God. We will never, ever become divine.”
“. . as Jesus is the Son of God.” Do you realize that you actually stated that Jesus is not divine?
Blasphemer!
No, I didn't. Are you admitting you think He isn't?
God the Father, God the Son, God the Holy Spirit.
Jesus is referred to many times in Scripture as God or Almighty God. He said that only God should be worshiped, but He accepted worship as His due. In John 8:58, He said, "Before Abraham was, I AM." In Revelation 1:8, He said, "I am the Alpha and the Omega, who is and who was and who is to come, the Almighty." As you see, He is fully divine, fully God.
