Good, sound research says that over 95% of the things that people worry about & which cause mental breakdowns, never happen.
‘Worry’ comes from a word that means being wolfed or eaten by a wild animal.
Eccl 11:10 in Moffatt's New Testament Banish worries from your mind and keep your body free from pain!
In the Greek New Testament worry means divide, rip, tear apart, etc.
1 Pet 5:7 Living Bible Let Him have all your worries and cares, for He is always thinking about you and watching everything that concerns you.
There is a lot of eschatological teaching about these days! That means a study of end time events. There is nothing wrong with that, except many of the 'teachers' of end time events cannot and do not relate that particular teaching to the position of the Church today, and in relation to the finished work of Calvary. Much of what is taught bears no relevance to where you and I are today and how we can better equip ourselves for these last days.
When people preach bad news, it's hard to reconcile that to The Good News that Jesus said we should present. When tough times come; the tough (in Jesus) get going with The Word!
Worry is like a rocking chair. It will give you something to do, but it doesn't get you anywhere!
Worry is like paying advance interest on a bill before it's due!
Worrying always does more harm to the one doing the worrying, than doing anything to change what is being worried about!
Yet so many Christians are still worriers in spite of what God says in His Word.
Jesus said in Luke 12:22-23,25-26,31
22 Then Jesus said to his disciples, "Therefore I tell you, do not worry about your life, what you will eat; or about your body, what you will wear.
23 Life is more than food, and the body more than clothes.
25 Who of you by worrying can add a single hour to his life?
26 Since you cannot do this very little thing, why do you worry about the rest?
31 But seek his kingdom, and these things will be given to you as well."
Jesus wants you to know you are very valuable to Him and the kingdom. His concern was that we reach for His kingdom; which is far greater and more valuable than anything in the world.
Worry is a demonic design which is powerless to accomplish good and yet very powerful to destroy. Jesus encourages you to reach beyond the struggles of this world and partake of the kingdom that He has already given you as His children. It protects and comforts while at the same time allowing survival.
If the world is overwhelming you, you should ask God to teach you how to release your worries. Rest yourself on Him, believing He has already completed what you need in your life. You will find it works and that worry is really a sin in light of all He has done and provided for you.
