“Do you not know that if you surrender yourselves as bondservants to obey any one, you become the bondservants of him whom you obey, whether the bondservants of sin (with death as the result) or of duty (resulting in righteousness)?” Romans 6:16 (Weymouth translation) God has an opportunity now for the Church class to be these righteous bondservants, but he has not left the remainder under the condemnation of Adam’s sin.  God will never force our free wills to do the right thing; serving God is a decision we make of our free will.  There will be an opportunity in Christ’s kingdom for the rest of the world of mankind to consecrate their hearts and lives to God.

What are the proofs for this?

In Acts 15:14 (NASB) “God first concerned Himself about taking from among the Gentiles a people for His name.” 

These have the opportunity for salvation first. Continuing Acts 15:17 speaks of another class “…the rest of mankind

[who] may seek the Lord…”  Both classes are referred to in Acts 24:15: “there shall be a resurrection of the dead, both of the just (faithful consecrated Christians) and unjust (the rest of the world).” 

“For as in Adam all die, even so in Christ shall all be made alive”(1 Corinthians 15:22).  Now all die – so it will be equally true in God’s Kingdom that all will be made alive. During that time, the blindness Satan has caused to fall upon men will be lifted. (2 Corinthians 4:4; Jeremiah 31:33,34)

Scriptures need to be applied in their proper time period. When Christ establishes His earthly kingdom, the opportunity to know God will be open to all. “The Spirit and the bride (the church) say Come. And let him that is athirst come. And whosoever will let him take the water of life freely.” (Revelation 22:17) At that time “the earth shall be filled with the knowledge of the glory of the Lord as the waters cover the sea.” (Habakkuk 2:14)

This answers the question of why God made the Bible hard to understand. Jesus, who was the best teacher ever, obscured His message to attract only a few. Matthew 13:10-11,  “And the disciples said…Why do you speak unto them in parables? He (Jesus) answered…Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.” 

It also answers the question why an all-powerful God would allow Satan to blind some minds. (2 Corinthians 4:4) It’s not time yet for everyone to make an informed choice. But God does have a “Due Time.” 1Timothy 2:4-6  “[God] will have all men to be saved [those who are willing], and to come unto the knowledge of the truth. For there is one God, and one mediator between God and men, the man Christ Jesus;  Who gave himself a ransom for all, to be testified in due time.”
