Theological systems that reject the eternal security of the believer find motivation for outward deeds in earning or keeping one’s salvation. Lives are spent doing good deeds in hopes that they can merit the favor of God. But for those whose confidence rests in God’s saving power alone, we go forth serving Christ with joy and confidence. If our service goes unnoticed, we don’t care because we know God sees it and we serve to please Him.
I ask, then, has God rejected his people? By no means! – Romans 11:1
The fear of rejection is perhaps one of the more influential considerations in our decision making. The choices we make, the conversations we choose to have or avoid, the way we spend our money; many times, these decisions are guided by our desire to avoid being rejected by others. The desire for a lasting acceptance seems an innate characteristic of humanity. If we are fortunate enough to somehow make it as part of the “in” group, the inner circle, we often take whatever steps we deem necessary to remain as such. To be numbered among the people of God is the best inner circle there could be, the most glorious collection of people there has ever been. To be a sinner saved by the grace of God alone through the atonement set forth in Christ is to be truly blessed, and so it begs the question: can one ever go from being part of the people of God to being separate from the people of God? There have been erroneous systems of Christianity throughout the centuries that have argued it is indeed possible to lose one’s salvation. A sacramental Roman Catholicism argues for the necessity of works to maintain one’s place within the family of God. An Arminian Protestantism denies the Reformed doctrine of eternal security. Both theological systems fly directly in the face of Scripture’s assertion that once numbered among the people of God, there is nothing that could ever remove you. Yet it begs one final question though: could God Himself remove you? Again, the Scriptures are clear: by no means!
Books have been written to prove this point from Scripture, so we’ll forego a lengthy discussion on proving this point. We’ll simply echo what Paul says in Romans 8: those whom God predestines, he also calls, justifies, and glorifies. Salvation is entirely of God from beginning to end. Or perhaps more poignantly, once we have been united to Christ by faith, we cannot be disunited, and our sins, both past and future, are covered by His blood.
