Making disciples should be easy, but it is not,
Now the eleven disciples went to Galilee, to the mountain to which Jesus had directed them. When they saw him, they worshipped him; but some doubted. And Jesus came and said to them, ‘All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything that I have commanded you. And remember, I am with you always, to the end of the age.’
The message of the Gospel should be enough to win anyone over, and people should eagerly desire to be baptized, but the spirit of the age vigorously opposes the work of Holy Spirit.
Teaching disciples to obey His commands is another thing we must constantly practice. The human ability to backslide is repeated so many times in the Bible that we know following baptism, continuing Christian education is a must.
Pray for the teachers. They can backslide too, and when that happens you don't make disciples from all nations. You wind up with addicts to the zeitgeist who typically share the poison they have been fed with those around them.
