We would be impoverished today if we only possessed the treasures of the word of God in the "Old Testament" Scriptures or if we only knew the treasures of the "New Testament" Scriptures. Both the Old and New Testament Scriptures are given by the same eternal Father, inspired by the same eternal Holy Spirit, and fulfilled by the same eternal Word, the Lord Jesus Christ, who was with the Father from the beginning and who was sent from heaven to take on human flesh for our salvation (John 1:1-3,14). There is a profound unity between the Old and New Testaments. Both are divinely inspired by one and the same Spirit (2 Timothy 3:16). The Old Testament prepares for the New and the New Testament fulfills the Old - the two shed light on each other. The Old Testament prepared the way for the coming of Jesus Christ as the redeemer of all who would be saved through his sacrifice on the cross. The New Testament lies hidden in the Old and the Old Testament is unveiled in the New. That is why Jesus interpreted the Old Testament Scriptures for his disciples and explained how he came to fulfill what was promised and foreshadowed in the Old (Luke 24:27). That is why we read the Old Testament in the light of Christ's saving death and resurrection. Do you revere the word of God in the Scriptures - both old and new - and see their fulfillment in the Lord Jesus Christ?

"Lord Jesus, may your word take deep root in my heart and transform my way of thinking, discerning, and acting. May your Spirit open my ears to hear and understand the word of God in the Scriptures that I may revere and treasure both the Old and the New Testaments which God has prepared for all who desire to enter his kingdom of righteousness, peace, and joy. Help me to be a diligent student and faithful disciple of your word."

The Cloud of Unknowing, by Anonymous

How a man shall know when his thought is no sin; and if it be sin, when it is deadly and when it is venial.

BUT it is not thus of the remembrance of any man or woman living in this life, or of any bodily or worldly thing whatsoever that it be. For why, a naked sudden thought of any of them, pressing against thy will and thy witting, although it be no sin imputed unto thee--for it is the pain of the original sin pressing against thy power, of the which sin thou art cleansed in thy baptism--nevertheless yet if this sudden stirring or thought be not smitten soon down, as fast for frailty thy fleshly heart is strained thereby: with some manner of liking, if it be a thing that pleaseth thee or hath pleased thee before, or else with some manner of grumbling, if it be a thing that thee think grieveth thee, or hath grieved thee before. The which fastening, although it may in fleshly living men and women that be in deadly sin before be deadly; nevertheless in thee and in all other that have in a true will forsaken the world, and are obliged unto any degree in devout living in Holy Church, what so it be, privy or open, and thereto that will be ruled not after their own will and their own wit, but after the will and the counsel of their sovereigns, what so they be, religious or seculars, such a liking or a grumbling fastened in the fleshly heart is but venial sin. The cause of this is the grounding and the rooting of your intent in God, made in the beginning of your living in that state that ye stand in, by the witness and the counsel of some discreet father.
