Christ taught me that faith is the antidote to fear. He repeats it many times throughout the new testament for a reason. you have fear because you expect things to go wrong, you don't expect things to work out in your favor. maybe they won't, but maybe what God has in store for you is better than what you could ever imagine for yourself.
in the book of Mark, chapter 14, Jesus seems deeply troubled to his disciples. He tells them, "My soul is overwhelmed with sorrow, to the point of death." He then tells them to leave him so that he could go and pray by himself. Christ then journeys up to the top of a nearby mountain, and begins praying,
"Father, you can do anything. Don't make me suffer by having me drink from this cup. But thy will be done, and not mine."
Christ knew what his destiny was, and that was to suffer miserably and face his inevitable death which was crucifixion. this prayer exemplifies his faith, and overall bravery, that we must do our absolute best to emulate. Christ had faith that even though he did not want this horrible fate, that God's will is always better than his own. He had to go down this path so that he could save the rest of us.
giving up our will and our lives to God may seem scary. as human beings we want what we want, and we want it when we want it, which is usually right now. this is completely understandable, and even though i have full understanding of this concept, i still have astronomical difficulty with giving my will to God. but this is something we all must practice if we want to have inner peace, and a clean soul. our will very often clouds our judgment, and makes way for the invitation of sin. giving up our will is the biblical equivalent of 'going with the flow.'
who are we to know what's best for us? can any of us see into the future? we have enough to worry about, and God tells us to let Him worry about it. He is much more capable of handling the stress anyway. by having faith that His will is best for us, we remove the need for us to worry about what is going on. we may wish things happened differently, but as they say, pressure makes diamonds. how many times have you heard a truly strong individual say that they wished they had never gone through any of their hardships? it almost never happens.
next time you are entering a situation and you are full of doubt and fear, try replacing those feelings with faith that God has your back, and knows how to form you into the person you need to be. every plan i've ever had for myself pales in comparison to what the LORD had in store for me. you cannot put your identity in worldly things because if/when they leave, it will destroy you, and if they leave, they were not sent by God anyway, so good riddance.
