The only mammals that are completely adapted to underwater living are the whales, dolphins, and manatees. These mammals have fins and for centuries were considered fish, even though it was known that many of them were furry. It wasn't until around the 1600's that they were discovered to feed their young with milk, and so they were called mammals.
Like all mammals whales, dolphins manatees need to breathe air. They need air because they have lungs instead of gills. You have probably heard about the water spout of the whale. Really it is nothing more than water vapor forced from the lungs when the animals come up to breathe.
Whales are at home in the water, yet not at home. They need air from above. God tells us in His Word that the Christian who is truly saved by trusting in the Lord Jesus Christ as his only God and Saviour is not at home in the wicked world any more. It is true that the true Christian must walk and talk, and eat and drink, and work and play in the world, but the true Christian's home is heaven. God says in Colossians 3:1-2 "If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. Set your affection on things above, not on things on the earth."
The truly saved Christian must be careful that while he or she lives in the wicked world, he must not let the wickedness of the world live in him. Just as the whale comes to the top of the water often for air, the child of God must often come to God in prayer. It is when we talk to God in prayer that we enjoy the breath of heaven. God tells us to come often to pray so we do not faint and grow weary and troubled.
Are you a child of God? If you are, remember where your real home is. If you are risen with Christ, seek those things which are above. Set your affections on things above, not on things on the earth. For your life style is in heaven.
