Ah, did we but rightly understand what the demerit of sin is, we would rather admire the bounty of God than complain of the straithandedness of Providence. And if we did but consider that there lies upon God no obligation of justice or gratitude to reward any of our duties, it would cure our murmurs (Gen. 32:10).
God's purpose in promising to reward with heavenly and eternal honors the faithful service of His saints is to win them from the pursuit of earthly riches and pleasures, to sustain them in the fires of persecution, and to encourage them in the exercise of Christian virtues.
The promise to the Church is a promise of persecution, if faithful in this world, but a promise of a great inheritance and reward hereafter. In the meantime, she is to be a pilgrim body, passing through this scene, but abiding above.
Let us remember, there is One who daily records all we do for Him, and sees more beauty in His servants' work than His servants do themselves... And then shall His faithful witnesses discover, to their wonder and surprise, that there never was a word spoken on their Master's behalf, which does not receive a reward.
Many, I fear, would like glory, who have no wish for grace. They would [want to] have the wages, but not the work; the harvest, but not the labor; the reaping, but not the sowing; the reward, but not the battle. But it may not be.
