You that are yet in the flower of your days, full of health and strength, and, with all the vigor of your spirits, do pursue some one thing, some another, consider, I pray, what are all your beloveds to this Beloved? What have you gotten by them? Let us see the peace, quietness, assurance of everlasting blessedness that they have given you.
Pray study him a little; you love him not, because you know him not. Why does one of you spend his time in idleness and folly, and wasting of precious time, perhaps debauchedly? Merely because you know not our dear Lord Jesus. Why do you spend your 'money for that which is not bread, and your labor for that which satisfies not?'
John Owen, Communion with God
