What does the Bible say about being partakers of Christ?

According to Hebrews 3:14, we are made partakers of Christ if we hold steadfast the beginning of our confidence until the end. This assurance underscores the importance of perseverance in faith. True participation in Christ's redemptive work is evidenced by our unwavering belief in Him and His promises throughout our lives. This concept is foundational in Reformed theology, emphasizing that while our salvation is secure, evidence of genuine faith is our endurance in the truth of the Gospel.
