When a person looks in a mirror they see their reflection, sometimes they have to make adjustments based upon what they see. Nevertheless, it is an image of themselves. The same concept applies to God's Word. When we meditate on the Word of God we become what we have read.
The Word of God is our manual for life, the abundant life, the Zoe' God kind of life. As we read and meditate on the Word of God we become what we meditate on. See
2 Cor 3:18.
For instance, if you meditate on negative thoughts you become a negative person, always seeing the downside of life, work and people.
Start seeing yourself the way God see's you, victorious, successful, more than a conqueror, beautifully and wonderfully made, most of all "Accepted in Christ!"
