1) Your body is a temple of the holy spirit.
1 Corinthians 6:19 says:
“. . . Do you not know that your body is a temple of the Holy Spirit who is in you, whom you have from God, and that you are not your own?”
2) Smoking is a bondage.
God doesn't like bondage.
Exodus 6:6 says:
"Therefore say to the children of Israel: ‘I am the LORD; I will bring you out from under the burdens of the Egyptians, I will rescue you from their bondage, and I will redeem you with an outstretched arm and with great judgments."
