Faith is the substance of things hoped for, the evidence of things not seen. Faith is tangible and has always been obedience to God’s plan (Word).
God gave Noah a plan and by faith Noah obeyed and built the Ark; which was the substance of things hoped for (salvation) and evidence of things not seen (God’s judgement). Genesis 6
God gave Abraham a plan and by faith Abraham obeyed and offered up his only son, Isaac.

God gave His Disciples a plan and by faith they obeyed and built the Church, which is substance of things hoped for (salvation), the evidence of things not seen (God’s judgment).
In the New Testament books of Matthew (28:19-20), Mark (16:15-16), Luke (24:44-49), and John (3:3-7), we see God’s Plan. In the book of Acts we see how His Plan was carried out by His Disciples.
