'Pure' in the Bible

For this is what we boast about: Our conscience testifies that we have conducted ourselves in the world with pure motives and godly sincerity, without earthly wisdom but with God's grace especially toward you.

For we are not like the majority who peddle the word of God, but as from pure motives--but as from God--we speak before God in Christ.

For consider how much diligence this very thing—this grieving as God wills—has produced in you: what a desire to clear yourselves, what indignation, what fear, what deep longing, what zeal, what justice! In every way you showed yourselves to be pure in this matter.

For I am jealous over you with a godly jealousy, because I have promised you in marriage to one husband—to present a pure virgin to Christ.

But I fear that, as the serpent deceived Eve by his cunning, your minds may be seduced from a complete and pure devotion to Christ.

What I say in this confident boasting, I say not as the Lord would [with His authority], but foolishly.
