The Red Sea can only be parted when you get there. The Israelites could not expect the Red Sea to be parted while they were still in Egypt. The future may not be as easy as was hoped. After all, the Promised Land was occupied and in order to possess the land there were some major challenges and battles.
There is a lady who works at my place of work. For all her life she has lived in a small, self-constructed, wood and iron house. Recently the government built her, as part of the government’s reconstruction campaign, a complete brick and mortar house. But even after it was completed she did not move in. She was so concerned about getting curtains and cleaning the windows and packing her goods that she, in the process, continued living in her wood and iron home, when, just a few meters away stood her new home. She was waiting for the Red Sea to part (all problems solved) before moving.
You cannot see everything that lies ahead, you cannot prepare for every contingency that may be ahead. Don’t let that stop you from moving into the future and don’t let that stop you from possessing what God has for you!
