8 For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; 9 not as a result of works, so that no one may boast. Ephesians 2:8-9 (NASB)
It is very common in the visible church in our time to hear preachers and teachers and people within local bodies of believers to boast about all sorts of things pertaining to their salvation or walk. They boast about their confirmation, baptism, church membership, Holy Communion, keeping the Ten Commandments, living the Sermon on the Mount, giving to charity, and living a moral life. It is not uncommon to hear some even boast about their faith, but all boasting is rooted in good works, not grace.
