Christians lose nothing when they lose temporal things. Because honestly speaking, what did they lose? Their faith? Their godliness? The possessions of the hidden man of the heart, which in the sight of God are of great price? Did they lose these?
For these are the wealth of Christians, to whom the wealthy apostle said, “Godliness with contentment is great gain. For we brought nothing into this world, and it is certain we can carry nothing out. And having food and raiment, let us be therewith content. But they that will be rich fall into temptation and a snare, and into many foolish and hurtful lusts, which drown men in destruction and perdition. For the love of money is the root of all evil; which, while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows.” 1 Tim. 6: 6-10.
