The full assurance of sin put away ministers to a spirit of praise, thankfulness and worship. This, and this alone, is the basis of worship. It produces, not a spirit of self-complacency, but of Christ—complacency—the spirit which has Him as the object and shall characterize the redeemed throughout eternity.
Worship does not lead one to think little of sin, but to think much of the grace which has perfectly pardoned and of the blood which has perfectly cancelled its debt. It is impossible that anyone can gaze on the cross, there by faith seeing the place which Christ took, or meditate upon the sufferings which He endured or ponder those three terrible hours of darkness and still think lightly of sin.
When all these things are entered into in the power of the Holy Spirit, there are two results which must follow: (1) an abhorrence of sin, and (2) a genuine love of Christ, His people and His cause.
