2 Corinthians 5: 7 (because by faith we walk, not by sight)
One of the anguish of people occurs because they always have in mind what fate can hold or that will come tomorrow, feel insecurity for the family and constantly think about things that may never come to pass.
Obviously, seeing tomorrow is not our power, no matter how hard we try and for this reason sometimes we can not live in the present because the future desires choke us and limit our today. In that sense the apostle James James 4:14 tells us:
When you do not know what it will be tomorrow. Because what is your life? It is certainly a mist that appears for a little while, and then fades away.
In this verse we find the advice of santiago about the people who live in anguish for tomorrow and exhorts us not to despair even though our vision is limited to the contrary we should trust in the God who sees everything and trust our anguish and burdens in his hands.
God knows our present and tomorrow reason why we should not be anxious He knows and knows all the challenges we have to face and that is why he uses the apostle Paul with encouraging words for each one of us so that we can trust in him and we He says. "Because by faith we walk not by sight".

That is our hope "faith in God", because if we trust in God we will not be anguished for tomorrow because we know that we rest in Him and He takes care of us.
