"The great command to go out and preach the gospel was not only meant for the disciples but for us too. So the very last command "Stay here ....until the Holy Spirit comes and fills you with power from heaven" (Luke 24:49), is also for us. "Do not leave Jerusalem until the Father sends you what He promised.....In just a few days you will be baptized with the Holy Spirit" (Acts 1: 4-5).
Take time to think of what a cry of need there is throughout the whole Church. There is only one remedy to be found to enable us to gain victory over the powers of this world. It is the manifest presence of our Lord........ Only He can call His hosts for the great battle against evil. Our main prayer should be for the power of God on all His people - to give them power from on high to make the gospel in very deed the power of God unto salvation". (Andrew Murray)
