This is illustrated in the Bible passages where Jesus overcomes the temptations of evil:
...the tempter came and said to him, “If you are the Son of God, command these stones to become loaves of bread.” But he answered, “It is written, “‘Man shall not live by bread alone, but by every word that comes from the mouth of God.’”
Jesus knew: I already have all that I need in God. God is my life and my purpose. He supplies all that I need and I can not be afraid or tempted.
“If you are the Son of God, throw yourself down, for it is written, “‘He will command his angels concerning you,’ and “‘On their hands they will bear you up, lest you strike your foot against a stone.’” Jesus said to him, “Again it is written, ‘You shall not put the Lord your God to the test.’”
I already know that I am loved and cared for by God. I do not have to put God to the test. I am secure in my relationship with God, good.
Again, the devil took him to a very high mountain and showed him all the kingdoms of the world and their glory. And he said to him, “All these I will give you, if you will fall down and worship me.”
Then Jesus said to him, “Be gone, Satan! For it is written, “‘You shall worship the Lord your God and him only shall you serve.’”
God has already given me, and all His children, the spiritual Kingdom of Heaven. Evil tries to gratify itself, but our Kingdom is given to us freely by God and filled with spiritual beauty, joy, freedom and love. There is no hatred, fear or disease in our Kingdom. It is whole and peaceful. It is the reign of Love and Spirit within us — within our consciousness.
Every child of God has the power and ability to overcome these temptations of evil and see the Kingdom of Heaven within. No one is left out of this Kingdom. This will lead to individual peace and freedom for us and the world.
