The heart, as described in Scripture, represents our innermost being and must be guarded diligently, as it influences every aspect of life. Just as physical stress can harm the body, spiritual stress—caused by worry, striving, and fear—can lead to exhaustion, but Jesus offers a better way through abiding in Him. By remaining connected to Christ, like branches to a vine, we naturally bear fruit, live in His love, experience true joy, and find communion with God.
