There is no text that states that Christ ONLY reconciled possible future believers only.Elin said:Neither texts state that Christ over looked the sin of man.
Yes, God overlooked their sin because Christ reconciled to God those who believe in the Son,
by his atoning sacrifice for their sin, taking it away on the cross (Heb 10:4).
Their sin is gone.
Their sin being removed by faith in Jesus Christ,
God declares them "not guilty" of sin and rightwise/in right standing with him;
i.e., justified, righteous (Ro 5:17; 1:17), saved from his wrath at the final judgment (Ro 5:9; 1Th 5:9).
Christ said he came to die as a ransom for the sins of many, he did not say for the sins of all (Mt 20:28).
