Calvin's comments on the "not seen" nature of faith are poignant. He writes:
The character of God is the source of this type of faith. Faith is a gift of God (Eph 2:8) and the assurance and conviction of it are based upon the promise and power of God. God has told us what will come and He cannot lie. God has told us what He will do and He, as the omnipotent God, will bring it about.
How's your faith? Are you assured and convicted here in the shadowlands?
Waiting patiently for the full realization of that which I long for with assurance & conviction,
