LEARN, GROW, AND WORK IN THE VINEYARD OF THE LORD
How old are you spiritually? Obeying the gospel, and nothing more, is like being born, but refusing nourishment. It’s not how many years you have been a Christian that determines your maturity, but how much you have studied, learned, and rightly applied the Word of truth. Learn, grow, and work in the Vineyard of the Lord.
