For the grace of God has appeared, bringing salvation to all men,
instructing us to deny ungodliness and worldly desires and to live sensibly, righteously and godly in the present age,
Titus 2:11-12 (NASB)
The pure and the defiled
To the pure, all things are pure; but to those who are defiled and unbelieving, nothing is pure, but both their mind and their conscience are defiled.
They profess to know God, but by their deeds they deny Him, being detestable and disobedient and worthless for any good deed.
Titus 1:15-16 (NASB)
