There are two different types of blindness one being physical and the other being spiritual. Physical blindness is easy to recognize due to the outward signs that are shown but recognizing spiritual blindness requires maturity in the Word of God to recognize what is actually taking place. There are two different confirmations that take place within spiritual sight one being verbal and the other being in the signs.
Spiritual signs normally start in a small way but over time they can magnify in ways that one can not miss. The object is to recognize the spiritual signs and learn to seek God for the direction in moving forward. For there is nothing that we can do in the physical to hold something together in the spiritual but when we learn to allow God to hold things together in the spiritual is when we will find the unity of love within the physical…
Therefore what God has joined together, let man not separate…Mark 10:9
