7 For God has not called us to impurity but to live in holiness. 8 Consequently, anyone who rejects this does not reject man, but God, who gives you his Holy Spirit. (1 Thessalonians 4:7-8 CSB)
We have been called in this life to live a purely and justly as we can. Knowing that nothing we have to offer, save our faith, would ever be enough to save us. However, when we allow areas of our lives to go unchecked, this is a rejection of God not man.
We are given a Spirit to guid us and who will convict us of what is impure in our lives.
