God’s Kingdom is more than just a personal experience, it is also God’s intended will for believers who gather together—the church. Individually and collectively—we are called to overflow with His love, which brings God’s Kingdom to earth. And we are not to keep it all for ourselves.
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.”Acts 1:8, NIV
We are the church—a body of believers. In the early days of the church, as it was just beginning, believers practiced the act of giving as a weapon to overcome evil.
All the believers were one in heart and mind. No one claimed that any of their possessions was their own, but they shared everything they had. With great power the apostles continued to testify to the resurrection of the Lord Jesus. And God’s grace was so powerfully at work in them all that there were no needy persons among them. For from time to time those who owned land or houses sold them, brought the money from the sales and put it at the apostles’ feet, and it was distributed to anyone who had need.Acts 4:32-35, NIV
It wasn’t socialism or utopia, it was people living out the Holy Spirit fruits. And this is only possible through God’s grace.
This is to my Father’s glory, that you bear much fruit, showing yourselves to be my disciples.John 5:5-8, NIV
