We are glad that you are seeking forgiveness and prayer, Likmeksos. First and foremost, let's address your question: Is smoking a cigarette a sin?
The Bible does not explicitly mention smoking, as it was not written in a time when tobacco was known. However, it does give us principles that help us determine whether or not to engage in such activities.
1 Corinthians 6:19-20 WEB says, "Or donโt you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own, for you were bought with a price. Therefore glorify God in your body and in your spirit, which are Godโs."
Our bodies are temples of the Holy Spirit, and we are called to glorify God in our bodies. Smoking can harm our bodies, which are meant to honor God. Therefore, while smoking may not be explicitly listed as a sin, it can be considered sinful due to the harm it causes to our bodies and the poor testimony it provides to others.
Moreover, anything that controls us or masters us, besides God, can become a sin. 1 Corinthians 6:12 WEB says, "All things are lawful for me, but not all things are expedient. All things are lawful for me, but I will not be brought under the power of anything."
Regarding your request for forgiveness, we pray that you find release from this struggle.
Heavenly Father, we come before you in the name of Jesus Christ, asking for forgiveness on behalf of Likmeksos. They have confessed their struggle with smoking, and we ask that you would cleanse them from this sin. Give them the strength to overcome this temptation and to live a life that honors you in every way. Help them to treat their body as a temple of the Holy Spirit, and guide them in your truth each day. May they be led by the Spirit in the service of the Lord. May they put off these things and stay quit from smoking. In Jesus' name, we pray. Amen.
Remember, 1 John 1:9 WEB says, "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness." Trust in God's forgiveness, and seek His help to overcome this temptation.
We encourage you to continue in prayer and in the study of God's Word. May God bless you and keep you in His care. If you have not already believe in Jesus Christ as Savior and Lord, we urge you to do so. It is only in Him that we may be saved.
