Do you know anyone who doesn’t think he or she sins?
Christians are sinners who have recognized their sins, repented, and believe in Christ for salvation. Christians still sin, but when we confess our sins, God forgives (1 John 1:9).
Non-Christian sinners are everyone else. Some are those who rely on their behavior, believing their external adherence to God’s law or their ethical/moral standing makes them righteous and guarantees them a place in heaven. The Pharisees are a prime example, although there are many today, including within the organized church.
For the self-righteous, they have convinced themselves their standard is the one that counts with God. They are relying on external behavior. They are whitewashed tombs (Matthew 23:27).
Other non-Christian sinners do not believe they sin. They don’t believe in God, perhaps. They may believe only their opinion is right and cannot listen to alternative points of view. They may think whatever they do is right. Some claim they are perfect just as they are.
I saw a well-known athlete repeat a mantra: “I am perfect. I am strong. I am enough.”
If we say that we have no sin, we are deceiving ourselves and the truth is not in us. (1 John 1:8)
If anyone thinks he is something when he is nothing, he deceives himself.(Galatians 6:3)
Is it possible for either group ever to believe they are sinners in need of a savior?
The gospel contains both bad news and good news. The bad news is that we are all sinners and that sinners face a righteous, just God who hates sin. The good news is that God provided a Savior who died in our place IF we repent, believe, and trust in Jesus Christ, receiving Him as Lord and Savior.
I know nothing is impossible for God, and that He can bring anyone to confession, repentance, and belief. BUT….
God—Father, Son, and Holy Spirit—thank You that nothing is impossible for You. Please make us sensitive to the needs and opportunities of those who do not know You, who don’t think they need You. Please guide us.
