First, from Matthew 26:52:
Then Jesus said to him, “Put your sword back into its place; for all who take the sword will perish by the sword
The wisdom of this statement is readily apparent. Yet, there are times when it seems we are morally compelled to defend ourselves by "[taking] the sword." Personally, I believe this statement applies primarily to individuals and is not meant to dictate political positions -- Jesus was, after all, expecting the imminent coming of the Kingdom of God.
Second, from Mathew 6:
25 “Therefore I tell you, do not worry about your life, what you will eat or what you will drink, or about your body, what you will wear. Is not life more than food, and the body more than clothing? 26 Look at the birds of the air; they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not of more value than they? 27 And can any of you by worrying add a single hour to your span of life? 28 And why do you worry about clothing? Consider the lilies of the field, how they grow; they neither toil nor spin, 29 yet I tell you, even Solomon in all his glory was not clothed like one of these. 30 But if God so clothes the grass of the field, which is alive today and tomorrow is thrown into the oven, will he not much more clothe you—you of little faith? 31 Therefore do not worry, saying, ‘What will we eat? ’ or ‘What will we drink? ’ or ‘What will we wear? ’ 32 For it is the Gentiles who strive for all these things; and indeed your heavenly Father knows that you need all these things. 33 But strive first for the kingdom of God and his righteousness, and all these things will be given to you as well.
34 “So do not worry about tomorrow, for tomorrow will bring worries of its own. Today’s trouble is enough for today
I find such wisdom in the above. Having faith that tomorrow will take of itself is incredibly difficult. Plus, aren't we under an obligation to prepare for tomorrow? Perhaps what we can learn from this is that we cannot allow preparing for tomorrow to take away from the present moment.
Anyway, I would love to hear thoughts from my friends here at MDB.
