Live in peace without worrying about the future. Unnecessary worry and imagining the worst of scenarios will strangle your faith. Only God know what will happen to you The truth is that you're not even owner of the present moment, because even this one belongs to God. A) Yes who lives according to His will.
Every day there is enough with what God gives you to do ... no more or less is expected of you. Who are you to say to the Lord, "why are you doing this to me?" He is the Lord ... let him do what seems good to Him. In truth, you do not need to add your wisdom and your plans to His wise and good plan. Eating the fruit of your own wisdom is always a bitter experience. God allows this to show you how unpleasant it is to ignore His guidance. The future is not yours yet ... maybe it never will be. And when tomorrow comes, it's probably different from what you had imagined.
It is not enough to separate yourself from the ways of the world. You must also let humility be forged within you. The separation of the world it means not directing the course towards external things. When humility is formed in you, you will direct your course away from your own nature. All trace of pride must be conquered. Your pride in thinking that you know a lot about spiritual things is more dangerous than being a billionaire. Pride helps you believe that you are important to a much more subtle way.
Put aside your own interest, and simply let the will of God unfold around you.
Everything He does is for your good. Adore without having to see and know all. Keep up the good things you do, since you feel you have to do them and you can do them easily. Avoid things that distract you from Christ, and be careful that all your extra energy does not get you in trouble. Above all, live in the present moment and God will give you all the grace you need.
