"And a great windstorm arose, and the waves beat into the boat, so that it was already filling. But He was in the stern, asleep on a pillow. And they awoke Him and said to Him, "Teacher, do You not care that we are perishing?" " - Mark 4 V37, 38

"These things I have spoken to you, that in Me you may have peace. In the world you will have tribulation; but be of good cheer, I have overcome the world." - John 16 V33

The disciples faced the storm at the sea even while Jesus was with them. Being followers of Christ does not exempt us from the tribulations of the world and on the other hand tribulations are more in a Believer's life. Jesus let His disciples go through the storm but He did calm the storm and brought peace. Do not worry about the tribulations when you live with the Lord for the Lord will bless us with His peace.
