Human nature always wants to blame others; in reality each of us is to blame. It wasn't the nails that held him to the cross; it was His love for you. We each bear the responsibility; truly He died for you. He voluntarily gave His life.

But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. - Romans 5:8

I came here to give My life a ransom for many. - Mark 10:45

No one takes it [My life] from Me, but I lay it down of Myself. I have power to lay it down, and I have power to take it again. - John 10:18
