But can those who are converted to God perfectly keep these commandments?

No: but even the holiest men, while in this life, have only a small beginning of this obedience; (a) yet so, that with a sincere resolution they begin to live, not only according to some, but all the commandments of God. (b)

(a) 1 John 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 1 John 1:9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. 1 John 1:10 If we say that we have not sinned, we make him a liar, and his word is not in us. Rom.7:14 For we know that the law is spiritual: but I am carnal, sold under sin. Rom.7:15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I. Eccl.7:20 For there is not a just man upon earth, that doeth good, and sinneth not. 1 Cor.13:9 For we know in part, and we prophesy in part. (b) Rom.7:22 For I delight in the law of God after the inward man: Ps.1:2 But his delight is in the law of the LORD; and in his law doth he meditate day and night. James 2:10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
