And ye know that He was manifested to take away our sins; and in Him is no sin.
1 John 111. 5.

They that sin are enemies to their own life.
TobiT xii. 10.

TO choose sin is to reject Christ; to be ashamed, for fear of man, to do what Christ commands, is to deny Christ; to do, for fear of man, what Christ forbids, what is it but, with Pilate, to condemn Christ? for a Christian to be guilty of wilful deadly sin, what is it, but to crucify Christ afresh, and put Him to an open shame? Do what ye know to be pleasing to God, and avoid, by the grace of God, what ye know will displease Him, and God will enliven your penitence, and enlarge your faith, and brighten your hopes, and kindle your love. Only be very diligent, not knowingly to do anything which displeases God; be very diligent not to tamper with your conscience and do what you suspect may displease God.
Edward B. Pusey.

We can never cling to a besetting sin with one hand, and grasp Jesus Christ with the other. Until thou art content to reckon thyself dead indeed to every known form of sin, whether thou thinkest it small or great, thou never canst follow Jesus.
Wm. Hay M. H. Aitken.
