I only ask you one question, even if you prove that only certain people can be saved, then what is God doing all this for? Is evangelism still necessary? Someone could have been saved without The Gospel,but God wanted it.It is you that has misunderstood the meaning of many scriptures, which in your theory does not harmonize with each other
The "us" in Ephesians 1:4 are a specific people, and they are the saints witch are at Ephesus, and to the faithful in Christ Jesus, who have been, before the foundation of the world, predestined to be adopted as his children, bu Jesus Christ.
