"Therefore I will judge you, O house of Israel, every one according to his ways, says the Lord GOD. Repent and turn from all your transgressions, lest iniquity be your ruin. Cast away from you all the transgressions which you have committed against me, and get yourselves a new heart and a new spirit! Why will you die, O house of Israel? For I have no pleasure in the death of any one, says the Lord GOD; so turn, and live." Ezekiel 18:30–32 (RSV)
God takes sin seriously. He created us as free creatures able to know and love Him. Human beings have used that freedom to exalt themselves above God. We choose sin over the love of God. Our race lives under the mistaken notion that we are only truly human when we do whatever we want.
Living as if God does not matter or is unconcerned with sin is to choose death. We may enjoy what the world calls a 'good life' while here, but the grave cares little for our bank accounts.
'Why will you die?' The Father asked this of Israel, but it is His question to us all. Why do we choose eternity cut off from Him when He longs for each of us to be His forever?
The Father has no joy in the death of even the most wretched sinner. He would rather they repent of their sin and live. He gives His only Son to take sin and death into Himself so that sinners can be redeemed and forgiven. He gives the Holy Spirit to create and sustain faith.
Why will you die? It is so unnecessary, therefore repent and trust in the Father's promise of grace and mercy in Christ.
