What does the Bible say about knowing Christ and salvation?

In 1 John 2:3-6, the Apostle John explains that we can know we have a relationship with Christ if we keep His commandments. This obedience is evidence of our salvation, not the basis for it. It reflects a transformation that occurs when the Holy Spirit works within us, leading us to live in accordance with God's will. True knowledge of Christ is intimate and personal, rather than mere intellectual assent. It assures us of our salvation as we seek to walk in His ways, though we do so imperfectly due to our sinful nature.
