In a blog post entitled “My Biggest Sin,” McKay Caston writes:
You couldnâ€™t help it, could you? This is gonna be juicy, right? Could be. Okay, letâ€™s get to it. What is my biggest sin? Of course, most of us probably think of the Top 10 list in Exodus. â€œThou Shall Notâ€¦â€ But weâ€™ve all broken every one of those. No surprise there. So what is my biggest sin? Here goes: Not believing that I have been fully forgiven, totally accepted, and am dearly loved by the Father. Sorry to disappoint you, but when I DONâ€™T believe this, I get religious and become a Pharisee of sorts, who were the biggest sinners in Jesusâ€™ day (because of their prideful, â€œI can do it if you just show me the ruleâ€ hearts). To look upon the work of Jesus on the cross as my judicial substitute and to NOT believe that I am fully forgiven, totally accepted, and am dearly loved is to cheapen the gospel. To think that I can add anything of my own merit is to severely diminish Godâ€™s glorious grace. It is an insult to the blood of Jesus. â€œSo Lord, I believe. Help my unbelief.â€
Jonathan Edwards seemed to suggest the same. Â In his 25th resolution for his life he wrote:
25. Â Resolved, to examine carefully, and constantly, what that one thing in me is, which causes me in the least to doubt of the love of God; and to direct all my forces against it.
