Hi InTheLight, salvation occurs when God puts an individual spiritually in Christ. Once in, Christ says He will not cast out. Positional sanctification, being spiritually placed in Christ, occurs during our lifetime, and not before creation. When and if God credits our faith as righteousness, He sets us apart spiritually in Christ 2 Thessalonians 2:13.
And when does God "spiritually place is in Christ" and "credit our faith as righteousness"?
