What’s the point in engaging with people who claim atheistic convictions? If their worldview is such that they deny the God who gave them the very breath, reason and senses they are employing to deny what they know but suppress that truth, is there any purpose? The bible explains that whatever they believe, they will be without excuse. God’s divine nature eternal power is apparent through his creation.
From a human perspective there is no point engaging. If Cyril Smith didn’t repent he is paying the price for his perversions. However, that’s not the end. For God is rich in mercy and while we were yet sinners Christ died for us. He gave his life for all the unbelievers, rapists, atheistic abortionists, liars and perverts. Justice and mercy cannot co-exists from a human perspective but God, the creator of all things, who is truth, and love, can forgive all who truly repent.
