During my mission trip to Kenya (which I just completed), I teamed up with some local pastors and visited an orphanage. One of my teammates, Pastor Russ Madill, preached to the assembled leaders and children a great message from John 9 about Jesus healing a man blind from birth. The kids giggled as Pastor Russ reenacted Christ spitting into the ground, making mud, and pasting it on the eyes of the blind man.
His dramatic presentation grabbed their attention and reinforced, with humor, how God’s ways are powerful but hard to predict.
As we were driving back to the hotel, I thought, “kids love comedy. They also like magic. Wouldn’t it be great to show them that set?”
I was referring to a chemistry set I’d heard about years ago that people used to share the gospel. (I think this is an example but I’m not sure. It’s been a long time!)
You start out with a black liquid in a clear glass. That color represents sin. No matter what you do, you can’t brighten it. The fluid stays dark which illustrates how our hearts are evil and need a Savior.
But then you take some red liquid and pour it into the glass. You’d assume that the red color would get absorbed by the black and disappear, but it doesn’t. In fact, the red liquid removes the black; the whole solution becomes as clear as water.
How that happens, I can’t say; I don’t know the chemistry. But the reaction demonstrates that the blood of Jesus, represented by the red chemical, removes our sins.
“Without the shedding of blood there is no remission of sins.” – Hebrews 9:22
“The blood of Jesus His Son cleanses us from all sin.” – 1 John 1:8
The blood of Christ can clean up the darkest heart and make it like God intended–clear and pure.
“Create in me a pure heart, O God, and renew a steadfast spirit within me.” – Psalm 51:10
If you’ve given your life to Jesus, no one can see your sin any longer. The black sin in your heart has been purged by Christ’s sacrifice.
But no one can see the blood of Jesus either. As the chemistry set exhibits, both the black and the red liquids become clear.
How will people know that Christ has cleansed your heart?
You have to tell them.
“And they overcame him by the blood of the Lamb and by the word of their testimony, and they did not love their lives to the death.” – Revelation 12:11 (NKJV)
Spiritual realities aren’t visible. No one can gaze into your soul and see either the stains of sin or the blood of the Lamb. You need to explain how Jesus changed your life. Don’t keep the good news to yourself; share it with others so they, too, can enjoy inner cleansing and purity.
