Modern wisdom would have us spend much time discipling new believers.
But consider the following:
Philip had no time with the Ethiopian eunuch after his baptism (which occurred at salvation).
The Philippian jailor became a disciple in the middle of the night, and next morning, Paul was gone.
Paul was in Philippi for “several days” (Acts 16:12) and yet the letter to the Philippians is full of praise for their faith and good works.
In other cities, (for example, Thessalonica–three weeks, Berea) Paul was there only a short time before being thrown out of town.
I became a believer at age 11 through reading a children’s book and knew no other Christians for four years. Somehow I realized that prayer and reading the Bible were important, and after a few weeks I led the girl who lived next door to Christ, but other than that I had no contact with other believers.
I’m certainly not saying discipleship is unimportant, but in situations where it doesn’t happen, is the Holy Spirit enough?
