"We have already established that we are all made in the image of God. there is good in all of us.
Jesus was perfect and free from sin (free to have a relationship with God the father). We, however, are all sinful (I won't go as far as totally depraved) and not free to have a relationship with God.
The wages of sin is death - that means a spiritual death, cut off from God.
The payment for sin was sacrifice of an unblemished lamb (literally in OT times, metaphorically Jesus, the lamb of God).
Jesus died to pay for our sins. The he rose again to conquer death once and for all. For all eternity, he made it possible for his followers to have a right relationship with God.
Some people don't believe in God because the Holy Spirit has not awakened in them. There is nothing for them to yearn or to respond to.
Not everyone has ears to hear.
There is no concept of "you scratch my back and I'll scratch yours" in Christianity. Jesus has already paid the ultimate price. Any good we do for others is because of what he has already done for us. We love because he loved us first.
Salvation is, by grace, through faith in the Lord Jesus Christ."
