That defining declaration unique to lovers of God; we walk by faith, not by sight, is a text often quoted by some to prove just the opposite. The notion put forth calls us to be satisfied and grateful for the gifts, promises and supernatural activities of God that cannot be seen in the here and now.
Those in that mindset present their 'faith' as superior to the simpletons who expect miracles and intervention from God. They wear their 'later, not now' theology as a badge. And, of course, when they do not get the miracles they would not believe for, no further 'proof' is needed.
Yet when Jesus spoke to the Pharisee, Nicodemus, in the middle of the night He told him that unless one is born again he cannot see the kingdom of God. The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit. By implication Jesus is saying that once born again, one can see the Kingdom of God - can hear its sound.
Being born again is every bit the supernatural miracle as was the parting of the Red Sea. It's interesting to note that Jesus spent the entirety of his life of ministry doing what people could see, hear and feel. He straightened the woman's back who was hunched over for 18 years. When He cast out demons from a crazed wild man, he became visibly calm and fully sane. He spoke to a raging storm and made the sea as calm as glass. Should we say then that Jesus really wasn't walking by faith because God was showing, telling and presenting to Him physical realities? No, how silly. In fact those physical realities, those miracles, signs and wonders, those deliverances, even multiplying food for thousands and walking on the ocean were effects of faith.
All those physical realities were drawn to earth from the unseen spaces of heaven by faith's mysteriously powerful action. These activities were seen, felt, touched, heard and experienced by actual people in our environment. So, when we say we walk by faith and not by sight, we essentially are defying the physical limitations and realities that appear to our natural senses.
The superior substances of the unseen realm are disclosed by the Spirit to our understanding in the form of promises. Once believed, one persistently prays and affirms the promises, and by the operation of faith the promise breaks into our present experience.
A promise not believed never lands. Love only spoken, and not felt or understood, is love unfulfilled. Mighty power admired but not applied is just pie in the sky.
Faith in the abstract of our intellect brings salvation to no one. It keeps the kingdom of God, which is closer than our next breath, a billion miles from the hearts and souls and eyes and ears of real human beings.
Tell me, in the whole Bible, where God communicated to his people apart from manifesting activity that they could touch and see and hear and smell and taste.
We walk by faith, and not by sight. What, pray tell, do you imagine those words meant to Paul the apostle who also stated, "And my God will supply every need of yours according to his riches in glory in Christ Jesus"? Phil 4:19
Faith doesn't mean, "miracles are real, but they never happen here." The Bible teaches nothing of the sort.
Walking by faith exchanges the ordinary capabilities and limited experiences of our natural world for the works, the powers and matter (all that's possible) of the unseen, eternal world. It permits God's Kingdom in heaven to be our immediately present possession here and now. Not theoretically, as faithless religion purports, but fully tasted, felt, heard, seen and known.
