Know for your comfort that the weakest believer in Christ is as nearly related to God the Father as is the strongest believer. Every branch of a tree is either strong or big yet the largest limb and the smallest twig are equally united to the tree and therefore to the root, John 15:1-4. The weakest believer is clothed with the white raiment of Christ’s righteousness and is as much justified and sanctified as the strongest. There is no condemnation to all who are in Christ and even the weakest believer shall endure to the end. They are all kept by the power of God through Faith [Christ] to salvation. It is not the sinner that believes strongly that shall be saved but him for whom the LORD Jesus has been made... “...wisdom, righteousness, sanctification and redemption...that he that glorieth, let him glory in the LORD.”
