We are assured of our union with Christ through faith and the evidence of the Spirit's work in our lives.
The assurance of being united with Christ is grounded in faith that apprehends the gospel. As stated in 1 Corinthians 1:30, believers are in Christ because of God's sovereign decree, which predestined them to be conformed to the image of His Son. This union is confirmed through the Spirit's work, who quickens the heart and enlightens the mind to the truth of Christ's accomplishments on our behalf.
However, it’s essential to discern the genuine nature of this faith. Many profess to believe in Jesus but do not adhere to the Christ of Scripture. In Matthew 7:21-23, Jesus warns of many who will claim allegiance to Him without a true relationship. Thus, the true mark of those united with Christ includes not only a profession of faith but also a life reflecting trust, reliance on Him, and a yearning for His presence. Those genuinely united with Christ will experience the transformative power of the gospel, realizing their need for grace amidst personal affliction and spiritual poverty.
