When I first read a comparison of Jesus Christ and Noah's Ark, it triggered lot of interest in me and I spend days meditating on it and God revealed to me some great understanding of it, since them I used this analogy in many ways to explain walking with and growing in Christ.
The events in Old Testament were the shadow of things that come to pass in the New Testament. Now, those who are in Christ are saved, in Noah's time those who were in the ark to got saved. The ark represented Christ;
It is interesting to see what it is like being in Christ with respect to being in the ark. To understand this we need to know a bit about the structure of the ark, (Genesis 6:16 A window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; with lower, second, and third stories shalt thou make it.) the bible states that the door was on the side.. it had three stories and the window was on the top a cubit from above.
Since the door is on the side, and considering the fact that the ark was set on dry ground, those who enter the ark, would enter the lower deck and the window is only one cubit from above, so it must be in the upper deck, the only ventilation for the ark.
All who entered the ark are saved, irrespective of the deck they are in. So does it matter which deck they are in?
We know that all kinds of animals and birds were in the ark; obviously the larger mammals might be in the lower deck and those who travel in the lower deck will have to travel with them. Even if you don’t get crushed, it will be dark and stinking down there and though you will reach your destiny, you will never be able to enjoy your journey.
Now if we move to the middle deck? It will be better, there you don't have to worry about being crushed by an elephant, but there too it stinks and that dropping from all the birds all over you. It’s better than the lower deck still not what God intended you to have.
What makes the top deck different? It has abundance of fresh air and light. Jesus is the light of men (John 1:4 In him was life; and the life was the light of men.) and the Holy Spirit is often related to moving air, wind, breath etc., so the top deck represents the abundant presence of Jesus and Holy Spirit. So to enjoy the trip you need to be on the top deck, staying in the bottom deck and complaining won’t help. God has provided us what is needed, now it’s our turn to acquire it.
It’s the same being in Christ, even though that gets you a berth in heaven, to enjoy your life one need to grow in Christ.
To grow in Christ is to become like him, for that first we need to know him, to know him we need to spend time with him, communicate with him, and be in his presence. Climb on to the top deck, be in his presence and enjoy the trip.
(Psalms 37:4-5 Delight thyself also in the Lord: and he shall give thee the desires of thine heart. Commit thy way unto the Lord; trust also in him; and he shall bring it to pass.)
