We need to re-focus our minds so as not to be burdened by the distressful worries of our day that only affect our health. And worrying much will not solve the problems, like the bills to pay, the food to buy, the clothes we need, the relationships we need to mend. Jesus invites us to a solution. And where is that re-focusing? He says: "Come to Me all who are weary and burdened and I will give you rest" (Mt. 11:28). Is it necessary to worry? The Bible says: "Unload your burden on to Yahweh and he will support you; he will never permit the virtuous to falter" (Ps. 55:22; 1P 5:7). Of course, instead of worrying, do what you can, leave the rest to God.
Common sense may tell us this common proverb: "If you can do it, why worry; if you can't do it, why worry." The refocusing we need rather means trusting in God fully and endeavoring with all our might to seek to keep His will (cf> Mt. 6:33). Just be true to yourself and consider whether you are God's servant or a slave to money, worldly pleasures and things of the world. If you are God's servant, seek to do His will with all your heart, in the simple sincerity of a little child (cf. Mk. 10:15, Mt. 18:3).
