It for sure is a dance of differences regarding faith and hope… I looked up “substance” meaning having a depth of character and a value beyond superficial… as what Faith is made up of. God is and was faithful from the beginning. For it is God’s true substance unto us that he has done the work for us, yet we are being invited to honor and to participate with His faith along with our faith of agreement as it being done. This stirs up hope within us that God will turn things for our good. We grow in the process.
