The apostles wanted to know whether Jesus was going to restore the kingdom to Israel, but He told them that it was not for them to know, and He added this,
“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).
The Lord was in charge; all that they needed to do was wait, and then He would send them the power of the Holy Spirit, and they would travel extensively, declaring the things that they had seen and heard. When He sent the Holy Spirit upon them, and they preached, they changed the world forever.
You have changed your life because of what they testified.
