Now faith is the substance of things hoped for, the evidence of things not seen (Hebrews 11:1). Notice it says faith is the substance of things hoped for, in other words faith gives substance to what you hope for. Let me give you an example you will understand, everyone is familiar with a heating and cooling unit. If it is 80 degrees where you are and you want it to be 70 degrees, you set the thermostat on 70 degrees and that unit sends forth and releases the air(substance) that changes the temperature. But, notice that substance has to be loosed for it to change things and so does your faith. That unit is designed to change things and so are you. With the substance of faith in your heart you have the capacity to change things. For example, there was a woman with an issue of blood for 12 years. She did all she could do, she spent all her money, she saw all the doctors, but she was no better. She heard about Jesus and her chance was at hand, Jesus came walking by and she said, "If I may touch but his clothes, I shall be whole." She pressed her way through crowd and touched his garment and in an instant she was healed. And Jesus said, "Thy faith has made thee whole" (Mark 5:25-34).
Notice, one instance of loosing her faith changed her situation. Because loosed faith changes things. Jesus said it this way, "If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you" (Matthew 17:20). Notice if ye have faith ye shall say and there shall be a change. So if you are sick and all you do is speak sickness then you can't loose the substance that will change it. If you are broke and all you do is talk about how broke you are then you can't loose the substance that will change it. So instead of speaking the problem say what the word says about your problem, faith comes by hearing the word of God (Romans 10:17). And once you are built up in faith, out of the abundance of the heart the mouth speaks (Matthew 12:34). It will be more natural for you to speak the answer than the problem. And God promised his word would not return to him void, but that it would accomplish (Isaiah 55:11). So, don't give up, be patient he that promised is faithful. That thing can change.
And the biggest change you can make with your faith is from being a child of the world to being a child of God. That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God has raised him from the dead, thou shalt be saved (Romans 10:9). And as many as received him, to them gave he the power to become the sons of God. So, if you would like to become a son of God say this simple prayer. Dear God I believe Jesus died on the cross for my sins and that you raised him up from the dead and I confess now that Jesus is my Lord and Savior. Amen
