"But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth." -Acts 1:8 (NKJV)
Read the story of Pentecost in Acts 1:4-11 and Acts 2, or read it in a storybook Bible. How did you see the Holy Spirit at work in the story? What does it mean to be a witness?
To be a witness for Jesus means that we share the truth that we have experienced and heard. God takes care of the heart transformation.
Take out your map of the world, and point out any places familiar to your family. For the disciples, Jerusalem was their city, Judea was kind of like their state, and we can translate Samaria as their country.
On your map, locate and draw a circle around your own city using a pencil or your finger. Next, draw circles around your state and then your country. Discuss what it might look like to be a witness for Jesus in each of those regions.
