Here is a coloring page submitted by a reader from the Philippines named Carlos Bautista. He first created this Bible activity page about Nicodemus for their Vacation Bible School. This would be a handy lesson activity for your Sunday School lessons about Nicodemus seeking Jesus at night.
The picture shows Nicodemus in the top left corner wearing a hood under stars and the moon. Then the maze leads to Jesus who is seated at the bottom right of the page waiting for this nighttime seeker.
The inspiration for this free coloring page maze is John 3:1-21.
Now there was a man of the Pharisees named Nicodemus, a member of the Jewish ruling council. He came to Jesus at night and said, “Rabbi, we know you are a teacher who has come from God. For no one could perform the miraculous signs you are doing if God were not with him.” John 3:1-2 NIV
