Namoro e Sexo

13 Meats for the belly, and the belly for meats; however, God will destroy both it and them. Now, the body was not made for uncleanness, but for the Lord, and the Lord for the body:

1 Coríntios 6:13

3 And every one who has this hope in him purifies himself, even as He is pure.

1 João 3:3

for this is the will of God, even your sanctification, that you should abstain from whoredom- 
that every one of you should know how to possess his own body in sanctification and honor- 
not in the passion of lust, even as the Gentiles who know not God. 

1 Tessalonicenses 4:3-5
