How Firm is Your Foundation? Discover the power of building your life on belief, confession, repentance, and baptism, rooted in Christ’s promises. How Firm is Your Foundation is a question every believer must consider. Jesus reminded us, “But be on guard; I have told you all things beforehand.” (Mark 13:23). The hymn How Firm a Foundation, written in 1787, beautifully echoes this truth: “What more can He say, than to you He hath said?” Our firm foundation is built on belief, confession, repentance, and baptism. This is how we stand strong in faith when the storms of life arise.
