The complete unconditional love of God is so essential that it is difficult to express. And God is love, so it should be difficult to express in human words. Proof texting scripture to disprove God’s unconditional love is not, er… fruitful, at best.
And so in face of that difficulty, after all the scripture is quoted and all the ideas quoted, you come face to face with the eternal Son of God in Jesus Christ.
God needs nothing. He does not need human beings to be complete in his glory. God is love before God creates us to debate this issue. Father, Son, Holy Spirit; perfect love.
The fact that you even exist is proof that God’s love does not admit conditions, because you yourself are a contingent being. You didn’t create yourself, and you don’t deserve to exist, you exist purely because God’s love wills you.
And as a contingent being who is sinful, God did not vaporize you, but instead came into the world to save your sorry self.
If you don’t see that God’s love is without conditions, you are not seeing Jesus Christ.
