Isaiah 32:17 And the work of righteousness shall be peace; and the effect of righteousness quietness and assurance for ever.
One of the most precious redemption facts is the assurance that believers have in Jesus Christ. Christ did not die on the cross to hang a cloud of doubt over our heads. He came to this earth to impute to those who trust in Him a divine righteousness that provides assurance forever. Let’s be clear about this brethren, our assurance of salvation is not found in us, but in the Person and finished atoning work of Jesus Christ. Because Jesus declared it is finished, the gift that God gives to those who trust in Him is a righteousness and assurance forever.
This assurance we have in Christ is the catalyst of good fruit that brings glory to God. “And we desire that every one of you do shew the same diligence to the full assurance of hope unto the end.” Biblical assurance is not the result of sinless perfection, but of faith in Christ’s perfect obedience on my behalf and perfect sacrifice for my sin on the cross. When the church at Colosse was under fierce attack for teaching that was undermining the doctrine of the grace of God, that their hearts might be comforted, being knit together in love, and unto all riches of the full assurance of understanding, to the acknowledgement of the mystery of God, and of the Father, and of Christ. False doctrines will always attack the biblical doctrines of grace and full assurance. When Paul wrote to the church at Thessalonica, he said, “for our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance.”
Hebrews 10:22 Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water. Draw near to God with a true heart and full assurance of faith. Jesus has conquered death, He is risen and gives unto His children a living, eternal assurance.
