Before Jesus ascended to Heaven he commanded his disciples to go into all the world and proclaim the Gospel. However, you will notice that he instructed them not to carry out the “great commision” immeditely.
“I am going to send you what my Father has promised; but stay in the city until you have been clothed with power from on high.”
On one occasion, while he was eating with them, he gave them this command: “Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about. For John baptized with water, but in a few days you will be baptized with the Holy Spirit.”
Jesus made it clear. Altough he wanted his followers to continue his mission in his absence and go out into to the world to do the work of the ministry, he did not want them doing this without the Baptism in the Holy Spirit. The reason being is because the work of the ministry as well as the life of a Christian is tough work as it is. In addition to this, there are outside forces internal, external, and spiritual working against us. We need to be Supernaturally Empowered to do what we are called to do. Jesus also told his followers that this was indeed the purpose of the Spirits Baptism.
“But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.”
That is why I teach that being Baptized in the Holy Spirit with the evidence of Speaking in Tongues is the most important thing that can happen to a person next to being Born Again. I say, and as you can see our Lord does too, that once a person becomes a Christian they should immediately begin seeking the Baptism in the Holy Spirit so that they may be empowered to do the work God was called them to do, and be the person God has called them to be. If you have not received this blessing, seek it today.
