 If you've not submitted yourself to Christ, if you've not turned to Christ from your sin, then you are a Judas. If you have not heart, soul, mind, and strength in repentant faith and trusted yourself to your Creator to serve Him and Him alone, then you have a Judas heart. And like Judas, you have no excuse. What may be known of God? God Himself has shown it to you. His attributes, His eternal power in Godhead, His right to rule, His Word revealed to you this morning. But you've not glorified Him as God, you've suppressed the truth of Him in your unrighteousness, in your sin, then you have a Judas heart.
