Acts 1:18 (AMP)
"But you shall receive power (ability, efficiency, and might) when the Holy Spirit has come upon you, and you shall be Witnesses in all Jerusalem and all Judea and Samaria and the ends (the very bounds) of the earth."
Does God have the ability to do this?
The answer is YES.
Our reigning in Christ includes that miracle working ability to manifest heaven on earth. If I am an ambassador of Jesus Christ, I represent another kingdom. I walk in that kingdom's values and power. I personally think this is a long way from denominationalism. In the kingdom, He is grace, He is the principles by which we live, He is the culture of that foreign land that we belong to. In reality heaven is my home and the foreign land that I belong to is this earth.
God does not need many. Jesus worked with only twelve men and on the day of Pentecost there was only one hundred and twenty, but in Acts 17:6 it said these men have turned the world upside down. God just needs a few people with His power in them to accomplish His purposes on the earth. Power comes in proportion to your new identity. God's people have been born again, but not many have been trained to reign. Many of us have been trained in standards of the world, but we are now in God's family and we have a whole new set of standards. They are kingdom standards and they will set you out as being very different. I have eternal life and I live like I am already seated in heavenly places in Christ Jesus. In this kingdom, according to Romans 14:17, there is righteousness, peace, and joy in the Holy Ghost. It is a new life with different standards. We are to show people how good our God is. According to Proverbs 4:20-21, the Word of God can be like medicine for you. John 6:63 says my words are spirit and life. Reigning with Christ Jesus means that we understand the value and the power of God's word to change and transform our whole life, to bring us to a place where we aspire to go with God. God is giving to us the knowledge and the understanding as to what that means.
If you are prepared to walk in that reality, God will endow you with the necessary knowledge, wisdom, and power to reign in life by Christ Jesus.
