(for we walk by faith, not by sight:) we are confident, I say, and willing rather to be absent from the body, and to be present with the Lord. 2 Corinthians 5:7-8
Walking by Faith, dear Princess of God, and not by sight, means to live your life differently, with different eyes. Seeing with the eyes of faith, you will make different choices.
For example, it was the eyes of faith that enabled St. Maria Goretti to see that her purity was above even her mortal life. Normally, one can’t make such correct decisions – that is with only ‘sight’. That is why a deep and lively faith is so important.
Jesus says to Gabrielle Bossis in He & I, “the saints saw things differently from others and that is why they seemed to lead strange lives. They didn’t have the same eyes. “The atmosphere of the world is so false that it is foreign to truth. So go deep into My domain of love and lock yourself in.”
The truths of the Faith, dear Princess of God, are so important to hold as your convictions and to strengthen those convictions you can make daily mental prayer or meditations on those truths. A great source for truths of the Faith besides the Bible is the Catechism of the Catholic Church.
Walking by faith also means that you trust God no matter what the external circumstance of your life are, or what your internal mental, emotional, and spiritual life is. God never changes and is the same, yesterday, today and tomorrow and therefore by switching to an external focus, outside yourself, on God, you can achieve a certain stability and deep trust that will allow you to walk by faith and not by what you see happening in the world around you, or even your own inner world.
A Princess of God has faith that God is good and always wants what is best for her. She takes as her example, Abraham who trusted in God and His Plan even when what he saw didn’t make sense to him. She takes as another example, Job, who said Though he slay me, yet will I trust in him, when all around him, his life was in shambles and ruin.
