“13 Then He went up the mountain and summoned those He wanted, and they came to Him. 14 He also appointed 12 — He also named them apostles — to be with Him, to send them out to preach, 15 and to have authority to drive out demons.
16 He appointed the Twelve:
To Simon, He gave the name Peter; 17 and to James the son of Zebedee, and to his brother John, He gave the name Boanerges (that is, Sons of Thunder);
18 Andrew; Philip and Bartholomew; Matthew and Thomas; James the son of Alphaeus, and Thaddaeus; Simon the Zealot, 19 and Judas Iscariot, who also betrayed Him.”
Mark 3:13-19

Jesus gives us all the example we need for discipling other people. This wasn’t just a side priority for Him, this is the focus of His interaction with other people during His time on earth. Obviously, His main task was the purchase of forgiveness, but that was done on His own. His interpersonal efforts were all spent on discipling others.

This is the component of our faith that usually seems to be most difficult for people to undertake. Every Christian is called to disciple others. And Jesus shows us here that the process is not complicated from a ‘how to’ standpoint. We are never promised that it will be an easy process, but when it comes down to the ‘basic elements of what to do,’ it’s pretty straightforward:

Include people in what you’re doing in your daily walk with Christ.

Jesus invited them along.
We invite someone along.

He appointed them as His disciples.
We explain to people that we would like to have them join us and to what end. We designate it as a special relationship.

He was with them.
We spend time with them.

Jesus was preaching, so He taught them to preach.
Whatever ministry we perform, we invite them along with us to do the same thing, training them to do what we do.

He gave them authority.
We give people opportunity to do things on their own, and not just easy things. They need to experience what we’re doing first hand.

And then we send them out to do the same.
Those are the simple steps. The process isn’t quick, and it will involve your time. But this is the model Jesus laid out for us. It requires interaction, it requires love. It requires an investment of our lives. We cannot invite people along and then just set them adrift. They need the anchor of another person, they need accountability.

Jesus did all this with the disciples, and so should we. It’s not enough to just receive grace and then hoard it for ourselves. Living and walking with Christ means bringing others along on the same journey. It requires that we die to self and selfishness in the process. We give of our self, we pour out our lives for them in fact.

It’s what Jesus did for us.
Why should we expect to do any less?
