This is the day which the LORD hath made; we will rejoice and be glad in it.
If only we could comprehend exactly what this verse is telling us. This is the day which the Lord hath made. Regardless of what this day holds, it is still *HIS* day and He is using it for our good (even if the day is not good from our point of view). Every day can be a good day if we just look at it as God's day,not ours.
The Bible tells us to forget yesterday and to not even think about it. It is gone. It is the past. It no longer matters. Learn from it but don't dwell on it.
God also wants us not to worry about tomorrow, because we are not even promised tomorrow. He wants us to stop and live today... completely live today. Not just wish that it would fly by because it's Friday or fill it up so that it goes quickly. He wants us to take time and slow down long enough to realize that this is *His* day. Today is like a clean white sheet of paper... It is up to us what we put on it/in it. So rip up the papers of yesterday and start with your brand new sheet(brand new day).
How are we using this day? What would we change if we knew this was the only day we had left and that tomorrow we would be gone. Did you know that today will be the very last day for thousands of people? Some won't make it into tomorrow.
So let us slow down and live this day to it's fullest and realize that this is the day that the Lord has made(given us) and let us use it for His Glory.
Matthew 6:34 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 thereof.
