Acts 1:5
For John baptized with water, but not many days from now you shall be baptized with (placed in, introduced into) the Holy Spirit.
Acts 1:8
But you shall receive power (ability, efficiency, and might) when the Holy Spirit has come upon you, and you shall be My witnesses in Jerusalem and all Judea and Samaria and to the ends (the very bounds) of the earth.
Acts 2:2-4
2 And when the day of Pentecost had fully come, they were all assembled together in one place, When suddenly there came a sound from heaven like the rushing of a violent tempest blast, and it filled the whole house in which they were sitting. 3 And there appeared to them tongues resembling fire, which were separated and distributed and which settled on each one of them. 4 And they were all filled (diffused throughout their souls) with the Holy Spirit and began to speak in other (different, foreign) languages (tongues), as the Spirit kept giving them clear and loud expression [in each tongue in appropriate words].
As we celebrated Pentecost in the last week, it is just so good to be reminded of the fact that Jesus said to His disciples that they would be baptized by fire, that the Holy Spirit would come to empower them to be witnesses in Jerusalem, Judea and Samaria and that this all happened just as He said it would. The Holy Spirit was given when the whole assembly was gathered together in unity and in prayer. This same group of people that could not testify that they knew Him before (e.g. Peter) now became such powerful witnesses that 2000 years later you and I believe because of their testimony! What an amazing miracle wonder working God we serve!
Point to ponder: Come Holy Spirit, fill us again and again - make us Your witnesses in Jerusalem, Judea, Samaria and to the ends of the earth, so that 2000 years from now there will be those who will believe because of the testimony of Your Spirit through us!
