"FAITH is confidence that what we hope for will actually happen; FAITH gives us assurance about the things we can not see."
Do you only believe the things that are subject to your five senses? If you can not see it, or touch it, or smell it, or hear it, or taste it, then does it really not exist to you? Spiritual things may be a problem for you in that love and God may be difficult for you to analyze with your senses. All those who lived and waited for the coming of Jesus Christ, their Messiah, had to have FAITH! Then the Lord Jesus Christ came and for a generation, people were able to see, touch, smell, hear and taste the sweetness of the Lord. Since His death and Resurrection all people have not had that experience or pleasure. Once again our bond with the Lord is one of FAITH! The definition of faith is believing and perceiving as a real fact that which is not revealed to your senses. Do you have FAITH in the Lord Jesus Christ?
Do you have confidence as a child of God that your eternal future in heaven is certain? Do you hold the deed to your heavenly home even though you have not taken possession? Do you trust the Word of God and have full assurance and confidence that what He promised He will deliver? Some people believe that heaven is pie in the sky and they do not believe God or His promises. They do not have FAITH! They can not grasp the substance of things hoped for and they do not believe the evidence of things that are not seen or made clear to their senses. Even though some promises have not been revealed to our senses, as believers' we perceive them as fact and are confident that what we hope for will actually happen. Believers' are sure about the things they can not see when it come to the promises of the Lord! Because of God we have FAITH!
Based on your past experience do you believe that the sun will rise in the morning and set in the evening? That future action is not based on your senses, but instead on your belief and faith that what has occurred in the past will occur in the future. Repetition builds a muscle of memory and expectancy. You have confidence that what you believe and hope for will actually happen, the sun will come up. You have the assurance of your past memories and what you have experienced, even about things you have not seen or sensed. That is FAITH! It is funny that non believers' will exhibit faith about so many earthly things but fail to understand the truth and promises of God. They fail to trust God and His Word and His Son who came to earth and left us His Story. It is not blind faith that empowers the believers. It is based on their spiritual sense and knowledge and FAITH that God and His Word can be trusted, even more than their senses!
