For the Christian, this is an accurate statement. Our body is the temple of God because upon becoming children of God through faith in Christ, the Holy Spirit dwells within us.
1 Cor 3:16
Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?

It teaches us all things (John 14:26) and makes intercession for us with groanings that cannot be uttered (Romans 8:26). It also leads the Christian in obedience towards the Lord (Ezekiel 36:27)
Romans 8:9,14
9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
14 For as many as are led by the Spirit of God, they are the sons of God.

We often hear the statement “Our body is the temple of God” in regards to our eating habits and acts such as printing marks on our body. But the act that God asks us to refrain from because our bodies are his temple is not eating junk food, drinking alcohol or getting tattoos. Yes, these can be abstained from but we forget what the word of God says about a very popular act that the majority take part in…FORNICATION which can be summarized as all sex outside of marriage (premarital sex, adultery, homosexuality, incest etc)
1 Cor 6:18-20
Flee fornication. Every sin that a man doeth is without (outside) the body; but he that committeth fornication sinneth against his own body.
What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s.

God knows the dangers of sin and this is why he warns his children to flee!
Religion says: sex is GROSS
World says: sex is GOD
God says: sex is GIFT to be enjoyed in the context of marriage.

It is important for the child of God to remember that there is no sin that cannot be forgiven. We all fall short of the glory of God. But as a believer in Christ when we fall, God picks us back up, we can always confess our sins, ask for his forgiveness and the strength to resist sin’s temptations.
1 John 1:8-9
If we say that we have no sin, we deceive ourselves, and the truth is not in us
If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
