Jesus replied, “You are in error because you do not know the Scriptures or the power of God” Matt. 22:29
To know the scriptures is to know them intimately. The way a husband knows his wife.
To know the scriptures is to study, observe and pore over them; taking them in context and weaving them together a little at a time until a larger picture begins to emerge, until it grows still larger. In this way we begin to see how the Scriptures weave themselves together, their meaning from Genesis to Revelation.
To know the scriptures isn’t just memorizing words therein. A text without context is a pretext.
