Ether 2:25

And behold, I prepare you against these things; for ye cannot cross this great deep save I prepare you against the waves of the sea, and the winds which have gone forth, and the floods which shall come. Therefore what will ye that I should prepare for you that ye may have light when ye are swallowed up in the depths of the sea?

God would not stop the winds, waves, and floods that would make the Jaredites' voyage so perilous, because those very forces would propel them to the promised land, but he could prepare them to withstand the storms. God likewise will not remove every challenge, affliction, and trouble from our lives, for the opposition we face causes us to grow and propels us towards God, but he can prepare us and strengthen us not only to survive but to succeed.

Christ can still the storm around us, but usually he chooses to still the storm within us. We want instant answers, quick fixes, and immediate relief, but God wants us to become saints, and that is a process that takes time. He is there for us, cheers us on, and provides instruction and a helping hand through the roughest spots, but he will not do for us what we have to do for ourselves. He loves us too much to rob us of our ultimate victory by removing our temporary inconveniences.

Mormon 5:18

But now, behold, they are led about by Satan, even as chaff is driven before the wind, or as a vessel is tossed about upon the waves, without sail or anchor, or without anything wherewith to steer her; and even as she is, so are they.

Christ is both sail and anchor in our lives. A boat serves us when it can carry us forward in fair winds and shelter us in the storms. Without a sail, the wind does not help us; and without an anchor, the storms can carry us far off course. When we have faith in Christ, he will carry us forward and keep us on course, and he will not let the storms destroy us.
