Is it universalism?
God wants sons and daughters, not zombies who lack the freedom to think and to choose without coercion to love their heavenly Father.
Trinitarian theologian T. F. Torrance is on record for rejecting universalism because he sees in Scripture that, in the end, some people will believe while others will not. We can’t fully explain why this is; but neither can we fully explain the presence of evil in a world under God’s sovereign control (see An Introduction to Torrance Theology, by Elmer Colyer, p.54).
