How are we supposed to "make disciples of all nations"? This is no generic suggestion. No, this is a monumental and measurable assignment.
Jesus told his disciples specifically the means by which they would be able to accomplish the overwhelming task of sharing the gospel with all the people groups on earth. Look at Acts 1:8:
You will receive power when the Holy Spirit has come upon you; and you shall be My witnesses both in Jerusalem, and in all Judea and Samaria, and even to the remotest part of the earth. (Acts 1:8)
There are two things that we must note here. First, every person who is born again by repenting of sin and placing their faith in Jesus Christ receives the Holy Spirit (Eph. 1:13; Rom. 8:9). So, you have the power of the Holy Spirit working in and through you.
Second, every person in whom the Holy Spirit lives has been given spiritual gifts (1 Cor. 12:7). So, you have special giftings in order to help build up the church and reach the nations in specific ways.
What is our role in all of this? We must give the Holy Spirit sway over our lives.
Now, remember. If you are in Christ, then the Holy Spirit dwells in you. That doesn’t change. However, how much sway the Holy Spirit has over our lives does change is largely depends on us. Look what Paul says in Ephesians:
Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. (Eph 4:30)
Paul says this in the context of sinful behavior. The meaning is clear: When we sin we grieve the person of the Holy Spirit and his work in us and through us is affected. Then, these surprising commands:
And do not get drunk with wine, for that is dissipation, but be filled with the Spirit, (Eph. 5:18)
Paul commands us to be filled with the Spirit. And then in Galatians 5:16, Paul tells us:
But I say, walk by the Spirit, and you will not carry out the desire of the flesh. (Gal. 5:16)
We have a role to play in the Spirit's influence and power in our lives. In other words, we can do things to inhibit the Spirit's power working in us and through us and we can do things to enhance the Spirit’s power working in us and through us. Here is what we should do:
1. Repent of sin and flee from sin so that we do not grieve the Holy Spirit through our disobedience to God.
2. Practice spiritual disciplines in faith individually and in community. Things like studying the Scriptures, praying without ceasing, repenting habitually, giving thanks in all circumstances, and serving your neighbor.
When we live a life of avoiding sin and practicing the disciplines, then Holy Spirit gains more and more sway over our lives. This gives us more spiritual power and makes our gifts more useful in contributing to the fulfillment of the Great Commission.
