5:18 Neither shalt thou commit adultery - If thou hast not been guilty of any act of uncleanness, hath thy heart conceived no unclean thought? Hast thou not looked on a woman so as to lust after her? Hast thou not betrayed thy own soul to temptation, by eating and drinking to the full, by needless familiarities, by foolish talking, by levity of dress or behaviour? Hast thou used all the means which scripture and reason suggest, to prevent every kind and degree of unchastity? Hast thou laboured, by watching, fasting, and prayer, to possess thy vessel in sanctification and honour?
5:6-22 There is some variation here from Ex 20 as between the Lord's prayer in Mt 6 and Lu 11. It is more necessary that we tie ourselves to the things, than to the words unalterably. The original reason for hallowing the sabbath, taken from God's resting from the work of creation on the seventh day, is not here mentioned. Though this ever remains in force, it is not the only reason. Here it is taken from Israel's deliverance out of Egypt; for that was typical of our redemption by Jesus Christ, in remembrance of which the Christian sabbath was to be observed. In the resurrection of Christ we were brought into the glorious liberty of the children of God, with a mighty hand, and an outstretched arm. How sweet is it to a soul truly distressed under the terrors of a broken law, to hear the mild and soul-reviving language of the gospel!
