7 It was by faith that Noah built a large boat to save his family from the flood. He obeyed God, who warned him about things that had never happened before. By his faith Noah condemned the rest of the world, and he received the righteousness that comes by faith. - Hebrews 11:7 NLT
Hello family, God showed favor (GRACE) on Noah. Now it is up to him (Noah) to take hold of that favor. And he does exactly that. Why does he act and obey on this favor extended to him? Noah acts on God’s command because he had faith in what God was telling him to do. Faith in hebrew is amanah (am-aw-naw’) wich is defined as support or agreement (see Strong’s Concordance). So Noah put his support in God and acted in Obedience.
If you don't have faith in something you are not going to trust it, you won't obey it, you may even distance your self from it. But if you do have faith in something you will act on it and draw closer to it. We sit in chairs every day having faith that it will support us when we sit in them. If we have any thought that the chairs strength was compromised we would fix the chair or get anew one all together.
6 And it is impossible to please God without faith. Anyone who wants to come to him must believe that God exists and that he rewards those who sincerely seek him. - Hebrews 11:6 NLT
Faith, Grace, Obedience! That is what saved Noah and his family not obedience alone or grace alone. These three are always connected. When God sends us on a mission we have His favor (GRACE). We can have faith that He will provide all we need to accomplish the mission. With faith there is no reason not to obey. God told you to move then move!
Much Love & God Bless
