“And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.” 
(Acts 13:39)

I have often thought, how very gracious it was in God the Holy Ghost, in directing His servant Paul thus to teach the church. The Lord well knew how many of His people of little faith are at times sharply exercised, by reason of the slenderness of this principle; so as sometimes from the temptations of the enemy, and their own misgiving hearts, to call in question whether they have the least measure of faith. And what a relief to the souls of all such ought it to be, and no doubt hath frequently proved, when they are here told, and from an authority which cannot err, that “all that believe;” whether strong believers, or weak believers; whether babes in Christ, or fathers in God: all are alike “justified from all things,” by Christ. And the reason is given. It is by Him. Yes! Christ’s Person and Christ’s blood and righteousness, are the sole causes of justification; and perfectly distinct from, and unconnected with, any other circumstance whatever. It is indeed a very blessed thing, and calls for great thankfulness in the hearts of those, whom grace gives the power to enjoy it; when a child of God is strong in the faith which is in Christ Jesus. But it never should be forgotten, at the same time, that it is not our faith, but Christ’s salvation, which is the whole security of the Lord’s people, and the weakest believer, as well as the strongest, are alike safe in Christ Jesus. “In the LORD shall all the seed of Israel be justified, and shall glory.” (Isaiah 14:25)
