"The Faith" - God's Gift "
So then, The Faith (cometh) out-of hearing, and the hearing through or by The Word of Christ (God)" Rom. 10:17.
The Faith is that body of truth, God-given (revealed), unto the recipient for Faith-Obedience. At the same time, the believers' response in faith-obedience demonstrates their personal faith.
FOR EXAMPLE: "By faith, Noah being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house..." Heb. 11:7.
In other words, the faith given (revealed) of God unto Noah was saving faith unto him and his household. As you can see, Noah's faith-obedience in building the ark demonstrated his personal faith unto salvation.
Needless to say, building an ark in the context of our time saves no one. Even so, the circumstances of Noah's time, when put into today's context, demonstrate our personal faith for learning.
