When thou passest through the waters, I will be with thee; and through the rivers, they shall not overflow thee: when thou walkest through the fire, thou shalt not be burned; neither shall the flame kindle upon thee. Isaiah 43:2
Take the above scripture and make it your own, by faith. His word is for you to lean upon.
You have to exercise your faith, even if it is still little.
Faith is like a muscle, the more you use it the stronger it gets.
Faith is not something one possesses, as one owns a house or something.
Faith can be compared with water, we have to make sure we'll keep it contained, that it does not evaporate or run away through the cracks.
Faith needs continuously being activated, using it any available opportunity.
By faith we see the Invisible, believe the Incredible, and receive the Impossible.
Unless the LORD had been my help, my soul had almost dwelt in silence. Psalm 94:17
At this moment, you're looking up against an enormous high mountain. This mountain is blocking out all light and even the warmth of the "sun".
This mountain is very real to you, for you see and feel the result of all that has passed in your life.
But thou, O LORD, art a shield for me; my glory, and the lifter up of mine head. Psalm 3:3
Take God's word for what it is worth and trust your Heavenly Father. He speaks to you through His word.
Walk humbly in His footsteps, willing to learn from your Teacher. Use your "textbook" often and allow this life to be your "classroom". Go for "high" marks ONLY and you will pass every grade with great success.
