Meditation means “to think deeply and continuously about something.” For a Christian, this means remaining in the presence of God and pondering each truth He reveals about Himself until it becomes real and personal in your life. This takes time. In His Sermon on the Mount, Jesus accused certain would-be followers of calling Him “Lord” and yet never doing what He told them (Luke 6:46). They had the correct truth in their heads, but it had never translated into obedience. When you meditate on Scriptures, the truth moves from your head to your heart and results in obedience. As the Psalmist said: “Your word have I hidden in my heart, / That I might not sin against You” (Ps. 119:11).
When you know God’s Word in your mind but not in your heart, it means that you have learned the principles and concepts and doctrines of God, but you have not come to know Jesus personally. You can reject a doctrine, or ignore a concept, or challenge a principle, but it is much more difficult to ignore a Person. You can have Scripture in your mind and still sin against God. There are those who can recite long passages of Scripture and yet live ungodly lives. However, you cannot have Scripture fill your heart and continue to sin against God. When God’s truth is allowed to touch the deepest corner of your soul, the Holy Spirit will transform you into the image of Jesus Christ. Don’t just read your Bible, meditate on God’s Word and ask Him to change your heart.
