"He said to them, “This is what I told you while I was still with you: Everything must be fulfilled that is written about me in the Law of Moses, the Prophets and the Psalms.” Then he opened their minds so they could understand the Scriptures." - Luke 24:44-45
I recently purchased a set of CDs that promised to open a whole new world of foreign language. These CDs were supposed to be the key that would bring instant understanding with very little effort. Well, after some time I disposed of them because I couldn't find the promised "key" to instant understanding.
As Jesus shared with the disciples, he didn't offer them a set of CDs or any other academic program. He opened their minds so they could understand the Scriptures. As a result, as time passed we read, "When they saw the courage of Peter and John and realized that they were unschooled, ordinary men, they were astonished and they took note that these men had been with Jesus." (Acts 4:13) Jesus is the "key" to instant understanding.
Don't be afraid to open the pages of your Bible. Pray for understanding and read on. The Lord will give what you need and each day you will find new insight from him. Take the whole Bible from Genesis to Revelation and look for the Lord on every page and you will find the "key" to instant understanding.
