When I come to the end of my life, I don't think I am going to say things like, "I wish I had spent less time talking with my wife," "All that time spent teaching my kids was a waste," "I wish I had spent more time sleeping, rather than being as productive as I could be," "I wish I had spent less time in prayer and reading the Bible," "I wish I had spent less time worshipping God and in fellowship with other Christians, learning and growing in devotion to this great God who I will live with for eternity," "All the time spent reaching out to neighbors with the hope of the Gospel, helping those in need any way I could, and preaching and teaching the Word of God was fruitless," or "I really should have spent more on my selfish desires, such as -------."
Paul's letter to the Ephesians says we should make the most of our time because the days are evil, and that the way to do that is to learn the will of God for each of us.
"...having determined their appointed times and the boundaries of their habitation, that they would seek God...though He is not far from us;" (Acts 17:26-27).
God is this one determining our time here on earth, and is pleading with us to seek Him--the one who has given us life, breath, and all things.
As hard as we try, we really cannot give ourselves more time than God has allotted. How are we using that time?
For me, it is a question of whether I am living my life with an attitude of pleasing myself and others or with an attitude of pleasing God.
