The unbelievers are no longer condemned until they are born again of the Spirit. Redemption has been provided for all sinners but redemption is not received until they believe in His Son, thanks to the Father for drawing them unto the Son to reveal His Son so they can believe in Him & be saved as our belief comes from God the Father by the grace of God.
You seem to be teaching partial atonement. In your teaching, Jesus blood is shed and touches all humanity, but it doesn't pay for their iniquity until the human invokes the blood to be activated by choosing to believe.
That, by the way, is not salvation by grace. Instead, it is salvation by works.
Hebrews 9:11-28 shows that anything the blood touches is effectually cleansed upon contact. There is no waiting until a person believes before the power of the blood is invoked.
But when Christ appeared as a high priest of the good things that have come, then through the greater and more perfect tent (not made with hands, that is, not of this creation) he entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption. For if the blood of goats and bulls, and the sprinkling of defiled persons with the ashes of a heifer, sanctify for the purification of the flesh, how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God. Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant. For where a will is involved, the death of the one who made it must be established. For a will takes effect only at death, since it is not in force as long as the one who made it is alive. Therefore not even the first covenant was inaugurated without blood. For when every commandment of the law had been declared by Moses to all the people, he took the blood of calves and goats, with water and scarlet wool and hyssop, and sprinkled both the book itself and all the people, saying, “This is the blood of the covenant that God commanded for you.” And in the same way he sprinkled with the blood both the tent and all the vessels used in worship. Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins. Thus it was necessary for the copies of the heavenly things to be purified with these rites, but the heavenly things themselves with better sacrifices than these. For Christ has entered, not into holy places made with hands, which are copies of the true things, but into heaven itself, now to appear in the presence of God on our behalf. Nor was it to offer himself repeatedly, as the high priest enters the holy places every year with blood not his own, for then he would have had to suffer repeatedly since the foundation of the world. But as it is, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself. And just as it is appointed for man to die once, and after that comes judgment, so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him.
Notice that the blood falls on many, not on all. Those for whom Jesus shed his blood have been purified by his blood "once and for all."
So, salvation is given to those God chooses, not to those who think they can pick God at their convenience. When God reveals His redemption to the sinner, their life is changed forever.
