Object Lessons on God’s Love and Forgiveness

1. God’s love can soften the hardest heart

Perhaps you think you’ve sinned too much, and God could never forgive you. Maybe you have a friend to whom you’ve spoken about Jesus, but her heart is as hard as stone and she doesn’t want to ask Him for forgiveness and trust Him for salvation. Luckily for us, God’s love is so powerful, it can turn “hearts of stone” into “hearts of flesh”. Before you perform this experiment, share this verse with your students:

“I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh.” (Ezekiel 36:26)

Perhaps it’s hard for your students to imagine how God could change a person’s heart. No worries– here’s a way to show them! Here’s what you’ll need:

Materials Needed:

2 eggs
vinegar
a glass

Directions:

A day or two before you are going to teach your Sunday School lesson, you’ll need to place one of the eggs into the glass, and fill it with vinegar. Let the egg sit in the vinegar. After 24 hours, it should be soft and yellowish. Rinse it off and bring it to class with the other egg. Show the students the hard egg and let them touch it. (You can boil it to avoid it breaking and making a mess in your class.) Ask them if there is any way to make this hard egg shell soft. Then, rinse off the softened egg and let the kids touch it and even bounce it on the table. Explain that this egg spent 24 hours in vinegar, which “magically” made it soft! When God’s love surrounds us, like the vinegar covered the egg, we can’t help but come out completely changed. His love softens even the hardest of hearts!

2. God casts our sins far away

Here’s an object lesson that clearly shows the nature of God’s forgiveness. Before you begin, read this verse to your students:

“As far as the east is from the west, so far has he removed our transgressions from us.” (Psalm 103:12 NIV)

When God forgives us, he casts our sins far, far away. He forgives us completely, meaning he doesn’t hold any of our sins against us once we repent. He throws them out so far away so that they can’t affect us any longer. God’s love and forgiveness is also complete– He doesn’t hold a grudge, or bring up our past sins later on, saying, “Remember when you did that bad thing?”

Materials Needed:

Ground black pepper
A plate
Water
Dish soap

Directions:

Pour some water into the plate. Sprinkle a bit of pepper all over the water. Dip your finger into some dish soap, and then into the pepper water. The pepper will “magically” spread out, away from the soap. Note: the less pepper you use, the more easily it will spread to the sides.

3. God took our sins upon Himself

When Christ died for our sins, he took our punishment for us. Read 1 Peter 2:24 with your students:

“He himself bore our sins in his body on the cross, so that we might die to sin and live for righteousness; by his wounds you have been healed.” (1 Peter 2:24 NIV)

Show the students how God’s forgiveness removes sin by performing the following experiment:

Materials Needed:

A plate
A glass
water
food coloring
a candle

Directions:

First, mix a few drops of food coloring into the water and pour some of the colored water onto the plate. Then, place the candle in the center of the plate and light it. Finally, as you explain that how Jesus took our sins upon Himself as he died on the cross, place the glass over the candle, and watch as the water rises into the glass, leaving the plate clean.
