What does the Bible say about assurance in Christ?

Assurance in Christ is fundamentally rooted in the divine initiative of God, where He first lays our iniquities upon Christ before we can have true faith in that redemption. This principle aligns with the Reformed understanding that any belief in forgiveness must be grounded in God's grant of mercy. In this way, the assurance we have is anchored not on our subjective feelings or actions but on God's definitive work in our salvation. The Scriptures affirm this through passages that speak of God's unchangeable promises and covenantal love toward His people.

When we consider our faith, it's important to realize that its authenticity is evaluated by what we see in Scripture as God's historical acts of grace. The Lord reveals His grace to us through His word, which becomes the foundation for our belief. Therefore, our assurance is based on the objective truth of Christ's atoning work and the promises of God that are unfailingly reliable, providing us with the confidence we seek amid spiritual uncertainty. The culmination of faith, then, lies not in our strength in believing, but in resting upon the completed work of Christ and the divine assurances given to us through the Gospel.
