No if's but's or maybe's
The apostle Peter considered the promise of universal salvation from sin.
"You are the children of the prophets, and of the covenant which God made with our fathers, saying unto Abraham, 'And in thy seed shall all the kindreds of the earth be blessed.' Unto you first God, having raised up his son Jesus, sent him to bless you, in turning away every one of you from his iniquities." Acts 3:25, 26.
All kindreds of the earth shall be blessed, not cursed eternally.
This promise is called the GOSPEL.
"And the Scriptures, foreseeing that God would justify the heathen through faith, preached before the Gospel unto Abraham, saying, in you shall all nations be blessed." Gal. 3:8.
Note
The promise embraces all of Adam's race, all nations, all families, and all
the kindreds of the earth. Each of these terms embrace all mankind, and
they are all employed to express the extent of the blessing.
All mankind SHALL be blessed. No if's and but's or maybe's.
The promise is positive, absolute.
3. All are to be blessed in the seed of Abraham.
St. Paul informs us that Jesus Christ is that seed. He writes "Now to Abraham and his seed were the promises made. He says not, and to seeds, as of many; but as of one, and to your seed which is Christ" - Gal. 3:16.
The promise is that all mankind shall be blessed in Christ. The Apostle repeats the same promise when he says, "As in Adam all die, even so in Christ shall all be made alive."I Cor. 15:22.
4. This promise is the Gospel; hence the Gospel is that all our race shall be blessed in Jesus Christ.
Well might this glorious truth be called gospel or good news!
5. The blessing of the promise is communicated to mankind by and through Jesus the Christ, the promised seed, and as all the nations, families and kindreds are to receive the blessing, Christ is very properly called "The Savior of the world." John 4:42.
Jesus Christ is NOT the potential Saviour of the world: He IS Saviour!
