Heart Transplant

“Above all else, guard your heart, for it is the wellspring of life.”  Proberbs 4:23

God looks at each and every one of us and proclaims that we need a brand new heart.  He’s not talking about the organ beating in our chest – but that which really makes us tick from the inside out.  God wants us to have a new heart that recognizes sin, mourns and repents of this sin, and treasures God’s forgiveness.  Having this heart transplant is literally a matter of life and death.

The process for this heart transplant begins with repentance.  What is the definition of repentance?  To turn away from sin – to believe what God says is the truth about you.  We were all conceived with a heart that doesn’t want to take responsibility for sin, a heart that doesn’t believe that sin is worthy of death.  The wages of sin IS death.  We know that we are powerless to turn because we are dead in sin, incapable of returning to God.

God reveals that our problem (as his people) is not outright disobedience – but its with the heart.  There is no such thing as a “safe sin”.  We tend to justify our sin because we haven’t done anything terribly disobedient or we haven’t done anything that isn’t being done by everyone else – or my sin is far less than what so and so has done!  But God is blunt, saying, the soul that sins shall die.  God demands perfection.  Every last one of us falls short of that.  Therfore, the result is death.

Our self righteousness can even run so deep that we find ourselves blaming God for the mess we’re in.  It’s as old as Adam saying to God, “The woman who YOU gave to be with me…she gave me the fruit of the tree, and I ate.”  Things haven’t changed.  Every one of us at one time or another has pointed the finger at others, even God, as the reason for our wrong-doing – as if this excuses our sin or removes us from any accountability before God.

Only in repentance can we be restored so that our thoughts, words, and deeds match God’s will.  It is not repentance that saves us; but rather repentance is the sign that I realize what God has done in Christ Jesus.  We are made right with God because prior to all else, Christ lived, died, and rose for us.  Sinful men and women can only be changed into new creatures by the marvelous work of God in Christ Jesus.  Through the atoning work of Christ, we are able to do the will of God – to answer gladly when the Lord calls.

The true and reliable source of life is in Jesus Christ.  How does God give us this new heart for life?  It’s a lot like the way you would receive a new heart if you checked into the hospital for a heart transplant.  Before you can receive a new heart, someone has to die.  Not only that, the person must be willing to give of their heart and it has to be a match or your body will reject it.  You see the similarities with Jesus, don’t you?  Jesus give us the new heart that God demands.

He made that possible by living the perfect life that God demands and dying the death our sin deserves on the cross.  An organ donor is only willing to give you their heart once they’re done with it, not a moment before.  Jesus willingly went to the Cross so that you could receive His heart – now!

And how do we treat this new heart?  We treasure it!  We treasure the new heart and forgiveness God has given to us.  We “cast away all our transgressions” or as Luther put it – our entire lives are lived in repentance – treasuring our relationship with God above all things.  We nurture our new heart with the Word and with the life-giving food of Christ’s body and blood.

Therefore, when we face sin and temptation, we TURN away from it and rejoice in the promises of God that give us strength.  When we face doubts and circumstances that take away our confidence, we TURN to the promises of our Baptism and the sure and certain truth that we belong to God and we have been given a clean heart and have been restored in salvation.
