All who have this hope in him purify themselves, just as he is pure.

1 Thessalonians 4:3-7 NIV
It is God’s will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control your own body in a way that is holy and honorable, not in passionate lust like the pagans, who do not know God; and that in this matter no one should wrong or take advantage of a brother or sister. The Lord will punish all those who commit such sins, as we told you and warned you before. For God did not call us to be impure, but to live a holy life.

2 Corinthians 7:1 NIV

so that you may become blameless and pure, “children of God without fault in a warped and crooked generation.” Then you will shine among them like stars in the sky as you hold firmly to the word of life. And then I will be able to boast on the day of Christ that I did not run or labor in vain.
