The world we live in is not a perfect a perfect world. Almost everything that happens is designed to take away our joy. As christians we should not allow circumstances determine our mood or take away our peace. Difficult situations may arise but one thing that is certain is that they won't last. Our mind is a very powerful place. Whatever we allow to dwell there and constantly meditate on with time will begin to affect our lives physically.
Depression is a very terrible state for anyone to be in. Nothing good ever comes out from it. People who have been victims of this can testify to this fact. It deprives us from a lot of things. Instead of struggling with these battles that lead to depression and anxiety it is better we hand it to God.
Philippians 4:6 - Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
The cares of this world are too many if we were to begin to count them. There's never an end to problems as long as this earth is considered. Peace is something that comes from within and not external factors. We can't decide on what should happen. It is completely out of our hands. But we can decide to be happy or not. This is entirely up to us.
If we are to observe some people we come across with that seem all happy and cheerful it may amaze us to know that these people have problems that are even bigger and more serious than ours. But they decided not to let it to consume them. It's usually our attitude towards trying times that determines how strong or weak we are.
