Time:

 it's ours to spend, but not ours to keep. 

Time is a gift from God. Every breath we take comes from Him. We are stewards of His time. Our purpose, as stated in the Westminster Catechism is "to glorify God and enjoy Him forever." That is why we are here; for His glory and purpose. We don't deserve any of His blessings. The one thing that we do deserve is His anger and wrath. It is through His grace that we wake up each morning. It is through His grace that we are alive at all. We are living on "borrowed time."
So what are we doing with that time?
Are we using it to bring glory to God?
Are we pointing others to Christ though our behavior, speech, and thoughts?
Are we seeking the will of God for our lives or are we going to church on Sundays and living for ourselves the rest of the week?
Are we making a conscious decision each and every day to "seek first the Kingdom of God"?
Do we pray without ceasing, having God always on our minds? or do we waltz through the day ceremoniously offering a few words of thanks before we eat and possibly lifting up a few words in His direction before we climb into bed?
How do you spend your time?

"Time is free, but it's priceless. You can't own it, but you can use it. You can't keep it, but you can spend it. Once you've lost it, you can never get it back." ~Harvey MacKay

"Time is the coin of your life. It's the only coin you have, and only you can determine how it will be spent. Be careful lest you let another person spend it for you." ~Carl Sandburg

"Half of life is spent trying to find something to do with the time we have rushed through life trying to save." ~Will Rogers

"In truth, people generally make time for what they choose to do; it is not really the time, but the will that is lacking." ~ Sir John Lubbock

"He who would make serious use of his life must always act as though he had a long time to live and must schedule his time as though he were about to die." ~Emile Littre
