So you (Robert) have God the Father who sees all people everywhere as being "perfect and complete" (your words) in Christ; God the Son who offered Himself for all people for the forgiveness of sins, but knows that either He or His Father will change their mind at some point, and God the Holy Spirit still " calling people to come to Christ" even though they are already viewed as perfect and complete in Christ?
I don't expect you to understand anything. The Bible was written by Christians for Christians. I don't think that you are a Christian so you don't understand what the Bible is saying.
