Hebrews 11:1 "Now faith is confidence in what we hope for and assurance about what we do not see." I love this verse because it is the very meaning of faith. Faith is confidence for what we hope is true, and assurance for the things we cannot see, which include God, Jesus, and the Holy Spirit. Although we cannot see Them in the flesh, if you and I truly believe in Them, then our faith is all that matters.
