Yielded up here means Christ voluntarily gives up His Spirit in His body! To forgive sin means to remove those sins from oneself! Only God is able to do that for us! To forgive sin is not to disregard them or do nothing about them, but to liberate a person from them! That is to remove the guilt and power of sin over and in a person! We are to ask God to forgive us our sin and remove them from us so we do not stand guilty of them and under their power and control. Christ has forgiven us and He also asks us to forgive others! Remember our forgiving others is a sign of our salvation but only Christ has the power to redeem others! This is why Evangelism is so important! I can forgive a snake for biting me but if I go back to that snake he will bite me again! You can forgive that poor devil but he is still a devil. The sinner must still come to the same Christ we have come to! One sign that you have forgiven a sinner who has offended you is that you regularly pray for them that God will Bless them and that they will find Christ as their Savior! James and Hamsa Sasse.
