Until a man comes to the Word with the humility of a child, though he may may know much, he will comprehend little. Given the right attitude, the key to understanding Scripture is work. There is no substitute for study. Zealous effort is required to gain knowledge in any field of endeavour. This is true of music, science, or sport.
Bible knowledge is no different.
The basic principle of sowing and reaping applies. The greater the labour, the greater the reward. Many will fail to discover th ehidden treasures of God's Word because they will not make the effort. A desire to understand the Bible warrants continual activity of Scripture in the mind. This must include meditation.
