Charles Spurgeon Commentary Matthew 10:39

"He that findeth his life shall lose it; and he that loseth his life for my sake shall find it." — Matthew 10:39 (ASV)

If to escape from death, he gives up Christ and so finds a continuance of this poor mortal life, by that very act, he loses true life. He gains the temporal at the expense of the eternal. On the other hand, he who loses life for Christ’s sake does in the highest sense find life, life eternal, life infinitely blessed. He makes the wisest choice who lays down his life for Jesus and finds life in Jesus.
