trust in the Lord.

Why is the phrase "trust in the Lord" sometimes so hard?
There are moments where life can be so hard. There are times when we don't know how everything is going to work out. There are days where we don't feel like we can go on.
The reason I feel that simple phrase can be so complicated sometimes, though, is because we are human. We can't see the whole eternal scheme of things. God has a plan that is so much greater than we are and as children of God here on this Earth, out of His presence, we are limited in our understanding of just how beautiful and perfect the plan is that God has for each and every one of us.
Alma 5:13 "And behold, he preached the word unto your fathers, and a mighty change was also wrought in their hearts, and they humbled themselves and put their trust in the true and living God. And behold, they were faithful until the end; therefore they were saved."
Gordon B. Hinckley, before he passed away, was a prophet of The Church of Jesus Christ of Latter-Day Saints and I love his wonderful words of wisdom that he gave. In this particular instance he is talking about trusting in the Lord.
 “Things work out, it isn't as bad as you sometimes think it is. It all works out, don't worry. I say that to myself every morning. It will all work out. If you do your best, it will all work out. Put your trust in God, and move forward with faith and confidence in the future. The Lord will not forsake us. If we will put our trust in him, if we will pray to him, if we will live worthy of his blessings, he will hear our prayers.”
― Gordon B. Hinckley
I, too, know that when we put our trust in the Lord, when we have faith that things will work out and if we do our best to live how He wants us to live our lives that EVERYTHING will work out.
