God gives us sufficient grace for the tasks at hand each day, in order for us to avoid being weary, worn out, tired, or wanting to faint. However, in achieving this, we must learn to live one day at a time. Matthew 6:34 teaches us to meet each day's challenges as they present themselves and not to borrow trouble from tomorrow. If we learn to do that, then God's grace will sufficiently be made available to us to help us face and overcome all obstacles that come our way. BE BLESSED!
Take therefore no thought for the morrow:for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil therof. Matthew 6:34
