I do think we have to meet the conditions of repenting and having faith in Christ. In physical terms, the same way that a man who is cold and lost and in the dark needs to move towards a fire. It's a source of light and heat. If he faces towards it and moves towards it, he'll will get warmer and there will be more light. His shadow will be behind him. No matter how far away he is from the fire, there will still be some heat and light, the Fire is unconditional. The man did not and could not light it. But if he faces away and moves away from the fire, there will be soon be very little light and heat indeed. And nothing in front of him but his own shadow.
In spiritual terms, God is the author of things like light, love, sanity, holiness, forgiveness, life and all the fruits of the spirit.
Galatians 5:22-23
It's not a good idea to move away from those things. But the invitation and way has been made to all to turn, come forward and be a part of them.
John 3:19-21
