These verses show us the true cause of the loss of man's soul. Our Lord says to Nicodemus, "This is the condemnation, that light has come into the world, and men loved darkness rather than light, because their deeds were evil."
The words before us form a suitable conclusion to the glorious tidings which we have just been considering. They completely clear God of injustice in the condemnation of sinners. They show in simple and unmistakable terms that, although man's salvation is entirely of God, his ruin, if he is slost, will be entirely from himself. He will reap the fruit of his own sowing.
"God sent not his Son into the world to condemn the world, but that the world through him might be saved." There is no unwillingness on God's part to receive any sinner, however great his sins. God has sent "light" into the world and if man will not come to the light the fault is entirely on man's side. His blood will be on his own head if he makes shipwreck of his soul. The blame will be on his own door if he misses heaven. His eternal misery will be the result of his own choice. His destruction will be the work of his own hand. God loved him and was willing to save him, but he loved darknesss and therefore darkness must be his everlasting portion. He wouldl not come to Christ and therefore he could not have life (John 5:40).
The truths we have been considering are peculiarly weighty and solemn. Do we live as if we believed them? Salvation by Christ's death is close to us today. Have we embraced it by faith and made it our own? Let us never rest till we know Christ as our own Saviour. Let us look to him without delay for pardon and peace, if we have never looked before. Let us go on believing on him, if we have already believed. "Whosoever" is his own gracious word -- "whosoever believeth on him, shall not perish, but have eternal life."
