William Burkitt on Matthew 13:44

By the treasure hid in the field, and the pearl of great price, are understood, Christ, the grace of the gospel, and the way to life and salvation therin discovered; he that is thoroughly convinced of the worth and excellency of Christ's grace, will part with all that he has to purchase and obtain it.

Learn, That the sinner who will have interest in Christ, and a part in gospel grace, must part with all that he has to purchase and obtain them, even with his goods and lands with his wife and children; for Christ and his grace are a real good, a substantial good, a durable good; he outbids all the offers the world can make, and therefore it is our wisdom to part with all for him, and especially our sins, dearer to us than all the rest.
