Avoid trivial pursuits. You are a child of God, destined for glory, and called to do great things in His Name. Do not waste your life on hobbies, sports, and other recreational pursuits. Do not throw away the precious moments of your life on entertainment, movies, and video games. Though some of these things can properly have a 'small place' in the Christian's life, we must be careful not to give undue attention to temporal and fruitless activities. Do not waste your life. Employ the time of your youth in developing the character and skills necessary to be a useful servant of God.
Instead of consuming their leisure hours in vacant idleness, or deriving their chief amusement from boisterous merriment, the recital of tales of superstition, or the chanting of the profane songs of the heathen, they passed their hours of repose in rational and enlivening pursuits; found pleasure in enlarging their religious knowledge, and entertainment in songs that were dedicated to the praise of God.The Antiquities of the Christian Church
The saint is many times most busy when he hath nothing to do, and may say more truly than Scipio the African, Nunquam minus solus, quam cum solus, I am never less alone than when alone.
Who would not abhor that vanity of Nero, in shoeing his horses with precious gold, and causing that costly metal to be trampled under foot in the dirt, which was worthy to be the materials of a crown for the highest head on earth! Am not I a greater fool than the former, and more vain than the latter, if I spend that time- which is infinitely more costly than gold or Bezer, as having relation to eternity - wholly in worldly talk, which might be employed in declaring and admiring the boundless perfections of the blessed God
I wish that I may never spend my precious time amongst Christians, as the Athenians, who never understood the worth of that commodity, used to waste it, only in telling and hearing of news; but as Christ amongst his disciples, in discoursing of things pertaining to the kingdom of God.
We remember, also, how that it is becoming increasingly difficult in these strenuous days for those who are desirous of studying the deeper things of God to find the time which such study requires.
Though our persons fall, our cause shall be as truly, certainly, and infallibly victorious, as that Christ sits at the right hand of God. The gospel shall be victorious. This greatly comforts and refreshes me.
