Forgiveness

Clean hearts

Science with a twist

Colour hearts cut from cotton fabric with washable markers, then wash out the “stains” with a bleach solution.

Discussion point: God will forgive our sins, no matter how bad they seem.

You will need some white cotton fabric (an old washcloth or pillowcase works well), washable felt tip markers, bleach, water and a bowl

  • Premix a solution of equal parts of water and bleach.
  • Cut a heart shape out of easily-bleached cotton fabric. Have your children colour all over it with washable felt tip markers. As they are colouring, tell them that the heart represents our hearts and the felt marks represent sin. Talk about what sins they might be.
  • Next, dip the heart in the bleach solution. As you do so, read 1 John 1:8-9: “If we claim to be without sin, we deceive ourselves and the truth is not in us. If we confess our sins, He is faithful and just and will forgive us our sins and purify us from all unrighteousness.”
  • Explain that God promises to take our sins that are as red as the red felt tip marker and make them white like snow, or as bright as the freshly-bleached fabric heart.
  • Next, read Isaiah 1:18: “…Though your sins are like scarlet, they shall be as white as snow; though they are red as crimson, they shall be like wool.” Take a minute to ask your children if they want to have stained hearts or washed hearts. Pray a prayer together from the kids talk with God section.

Allow your children to keep their fabric hearts as a reminder of God’s promise to forgive sins. During the week, when your children sin, ask if they have put some marks on their heart. Suggest that you pray together so that God can “wash” the sin from their hearts.
