Problems will certainly come. Problems in life is not about status or age. The poor faces ithem and the rich alike. The young are tormented with them as well as the old. There is no one who is exemped from these troubles. The Lord Jesus Christ told those of us who are his disciples that in this world we are going to encounter tribulations. He said that what we will see in the world will be tribulations. That is to say that the world has only tribulations to offers us. But thanks be to God because He had offered us a solution. He said that in Him we shall fine peace.
What we need is the peace of God. It is that peace of God that will keep us calm when we are facing tribulations. When our hearts are fixed trusting in Jesus, we will not have anything to fear. There will not be any problem which the world shall bring that shall be able to trouble us. So, beloved o the Lord, there is no other way to stay calm and untroubled in the face of tribulations that to trust in Jesus Christ. Trusting in Jesus Christ is the perfect way of remain calm in tribulation.
We should trust in the Word of God. We have our faith strong in the Lord. We should believe that everything which he had promised us, he will be able to perform them.
