And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
(Roman 12:2)

There is a old saying that you are what you eat.  If you eat healthy you will be healthy.  There is a spiritual law that you are what your mind thinks and dwells on.  If your mind is on the circumstances and trials of life then you will always be struggling your life.  If your mind and thoughts are on the living word of God, you will be blessed, prosperous and victorious in your life.

Blessed is the man who walks not in the counsel of the ungodly, Nor stands in the path of sinners, Nor sits in the seat of the scornful; But his delight is in the law of the LORD, And in His law he meditates day and night. He shall be like a tree planted by the rivers of water, That brings forth its fruit in its season, Whose leaf also shall not wither; And whatever he does shall prosper.
(Psalm 1:1-3)

When your eyes, heart and mind are on the living Word of God Almighty and the Lord Jesus Christ you are feeding on the living power of God Almighty that will never fail you or run out!  When your eyes, heart and mind are on the world you are feeding on death, corruption and limited by the powers of this world.

But immediately Jesus spoke to them, saying, “Be of good cheer!  It is I; do not be afraid.” And Peter answered Him and said, “Lord, if it is You, command me to come to You on the water.” So He said, “Come.” And when Peter had come down out of the boat, he walked on the water to go to Jesus. But when he saw that the wind was boisterous, he was afraid; and beginning to sink he cried out, saying, “Lord, save me!” And immediately Jesus stretched out His hand and caught him, and said to him, “O you of little faith, why did you doubt?” And when they got into the boat, the wind ceased.
(Matthew 14:28-32)

No matter what the circumstances or trials or sickness in your life, The Lord Jesus Christ and His Living Word is far Greater and Powerful living alive inside of you!

You are of God, little children, and have overcome them, because He who is in you is greater than he who is in the world.
(1 John 4:4)
My help comes from the LORD, Who made heaven and earth. He will not allow your foot to be moved; He who keeps you will not slumber.
(Psalm 121:2-3)
