Genesis 6:18 says, "...go into the ark..." That's what God spoke to Noah before the 'great flood'. And then in Genesis 7:1, the Lord also said this, "Come into the ark, you and all your household, because I have seen that you are righteous before Me in this generation."
Today, as the righteousness of God in Christ (2 Corinthians 5:21), the Lord is calling you to get in & remain in His 'ark' as well!
Let's look at the name Noah first. It's called 'Nuwach' in Hebrew, which means 'to rest, being quiet, settled down, comforted'. In short, 'Noah' means 'to rest'. In fact, his name 'Noah' was given prophetically by his father Lamech after he was born, saying, "This one will comfort us concerning our work and the toil of our hands, because of the ground which the Lord has cursed." (see Genesis 5:29)
How about the word 'ark'? 'Ark' is 'tebah' in Hebrew which means 'box', and the Lord asked Noah to build it with 'gopherwood' (like cypress wood) that's normally used to build house. So, this is a 'picture' of 'God's house', and we also know that the 'ark of the covenant' in the Old Testament is also a 'picture' of Jesus Himself, the King of Glory.
'Noah' is a 'picture' of you, and the 'ark' is a 'picture' of Christ.
So, when the Lord asked Noah to get into the 'ark', it's like today, God is calling you to 'find rest' in Christ, your 'ark'. And when you are in Christ, you are safe, even if the world around you is full of 'storms'! This happened to Noah too during his time! He just needed to 'rest' or get settled down in the 'ark', no matter what happened outside (i.e. the 'tsunamis', 'torrential rain', 'earthquakes', 'thunderstorms', 'troubles' or 'judgments' outside the 'ark').
"Pastor, you ask me to 'live in a box'? That's too small and narrow a thing!" My friend, this 'one' is no ordinary 'box'! This 'box' is in fact larger than 'heaven and earth put together'! Genesis 14:19 says He is the Possessor of heaven and earth, the Most High God! That's who Christ is! He is also omnipotent, omnipresent, and omniscient! So, if you end up in Mars, He's there! If you go to Jupiter, He's also there! And if there's a technology that flies you to the sun, He's there as well! That's how great He is!
People of God, like Noah in his time, remain rested in the 'ark' (i.e. in Christ), no matter what happens in this end-time. The Bible says Noah 'found grace in the eyes of the Lord' (Genesis 6:8). Today, you have also found grace (because of what Christ has already done for you on the cross). And when you are in Him, whatever 'waves' or 'storms' cannot 'touch' you! And even if you 'fall down' (due to the 'raging seas' outside you), you fall down inside the 'ark'! Praise God, you can stand up again because you are still in Him! Know also that He will not get you 'thrown out'! (unless you choose to 'throw yourself out') I've checked the Scripture, and there was no mention of Noah suffering any 'lack' or 'trouble' whilst 'in the ark'! In fact, Genesis 7:23 says 'only Noah and those in the ark' remained 'alive'! People of God, ONLY IN CHRIST, you are truly 'safe' and 'alive'! There's nowhere else! (John 14:6)
Beloved, as a believer, always know and remind yourself that 'you are in the ark'. Bring every aspect of your life (i.e. marriage, health, finance, business, ministry, career, etc) into this 'ark' as well! And the moment you know you are in the 'ark' (i.e. in Christ), know that there's no more 'pain', no more 'sorrow', and no more 'death'. Know that old things have passed away and all things have become new (2 Corinthians 5:17, Revelation 21:4-6), and don't wait till heaven! You can experience His goodness and blessing even right now on earth! Yes, you can, because you are already in Christ!
I end with this: If anyone IS (present tense) in Christ, he IS (now) a new creation. Old things have passed away, and all things have become new (2 Corinthians 5:17).
And by the time the door of the 'ark' was opened, what Noah saw was a (beautiful) 'rainbow' (Genesis 9:13). Beloved of God, stay in the 'ark' too, till you see your 'rainbow', and that's when you meet Him at His throne (Revelation 4:3).
