Burk Parsons (from Ligonier - working with RC Sproul) says it well (bolding mine):
"When I teach on the Great Commission, I often begin by asking my students, “What is Jesus’ primary emphasis in the Great Commission?” Typically, most students reply, “evangelism.” I then ask them to read the Great Commission from
Matthew 28:18–20, after which I ask my question a second time. The students quickly see that although the Great Commission includes a call to evangelism, it doesn’t actually contain the word
evangelism. What the students observe through more careful study of the Great Commission is that Jesus’ primary emphasis is on making disciples.
Making disciples certainly includes evangelism but is by no means limited to evangelism. The sort of disciple-making to which Jesus commissions the church involves much more, including baptizing and teaching.
Simply put, if we have only evangelized a people or a nation, we have not been obedient to the fullness of the Great Commission. In addition to evangelism, Jesus provided us with specific instructions that we are to baptize “in the name of the Father, and of the Son, and of the Holy Spirit,” and that we are to teach people “to observe all that I have commanded you.”
