Have you noticed that all of us tend to be self-centered and selfish? It comes to us so naturally. Have you also noticed that people easily sin against other people? It comes to us so naturally. Have you noticed that all people die? Some live a little longer than others, but death claims us all. What does this all mean? Are we doomed to simply serve ourselves, harm other people and eventually be claimed by death? Is there anything more than this?
The joy that we have as Christians to share is that there is forgiveness of our sins. Further our temporal death is not the end. There is life everlasting for Christians in the glorious mansions of heaven. There is also purpose and meaning in life as a Christian, now, in this temporal existence. Christians are called to live for Christ and thus be a blessing to others. Christians are enabled to live for others by God changing them to be greater and better than their natural state at birth. St. Paul reminds us of this wonderful truth when he states by inspiration of the Holy Spirit:
For the love of Christ controls us, because we have concluded this: that one has died for all, therefore all have died; and he died for all, that those who live might no longer live for themselves but for him who for their sake died and was raised. From now on, therefore, we regard no one according to the flesh. Even though we once regarded Christ according to the flesh, we regard him thus no longer. Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come. All this is from God, who through Christ reconciled us to himself and gave us the ministry of reconciliation; that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation. Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on behalf of Christ, be reconciled to God. For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.
(2 Corinthians 5:14-21 ESV)
