The Lord originally created us with six senses. That sixth sense, which isn't functioning in most people today, is faith. Faith can perceive unseen realities, just as our eyes and ears can perceive physical realities. We can train our five senses to acknowledge and accept that the input of faith is just as real as what we can see, taste, hear, smell, or feel. We can walk by faith and not by sight (2 Cor. 5:7).
