As you go, preach this message: ‘The kingdom of heaven is near.’ Heal the sick, raise the dead, cleanse the lepers, drive out demons. Freely you have received; freely give. - Matt 10:7-8
We are commanded to go and preach the Gospel, but Paul says he did it not with words but in demonstration:
For I resolved to know nothing while I was with you except Jesus Christ and Him crucified. I came to you in weakness and fear, and with much trembling. My message and my preaching were not with persuasive words of wisdom, but with a demonstration of the Spirit’s power, so that your faith would not rest on men’s wisdom, but on God’s power. 1Cor. 2:3-5
As a ministry to the world, I believe this is the solution to bringing heaven to earth. The church must return to its original purpose and that was to walk in the power of Holy Spirit demonstrating the Kingdom of Heaven is near!
