Romans 5:6-9 (New King James Version)
6 For when we were still without strength, in due time Christ died for the ungodly. 7 For scarcely for a righteous man will one die; yet perhaps for a good man someone would even dare to die. 8 But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us. 9 Much more then, having now been justified by His blood, we shall be saved from wrath through Him.
God loved us so much that he had his son Jesus Christ die for us. Christ died for all mankind! No one was left out when he took on the sins of man. Christ was beat, whipped and pierced. No one was left out! If God can use Saul who was persecuting the church and change his name to Paul, what makes anyone think that God can not us them?
