REDEEMER.
Supposing I saw a man tumble into a river, and I were to jump in and rescue him, I should be a saviour to him—I should have saved him. But when I brought the man ashore, I should probably leave him, and do nothing further.
But the Lord does more. He not only saves us, but He redeems us—that is, buys us back. He ransoms us from the power of sin, as if I should promise to watch over that rescued man for ever, and see that he did not again fall into the water. The Lord not only saves us from spiritual death, but He redeems us for ever that death can never touch us.
