Jesus, the master Teacher, certainly taught His disciples formally, but they also shared life experiences, traveling and breaking bread for a number of years together. He mentored them, modeled how to truly walk with God and ultimately trained them to be launched into the world for His glory. He encouraged them, He disciplined them, He rebuked them, and He loved them. Jesus invested His life into theirs and certainly did not send His "children" away to others for their education but "kept them" and "guarded them" (John 17:12) until it was time to send them into the world.
In a very real sense, Jesus homeschooled His apostles. Christian homeschooling looks a lot like how Jesus trained His own, and His "children" eventually went on to "turn the world upside down" (Acts 17:6)!
Today many Christian parents are waking up to the fact that no one can do a better job in training and discipling their children than they can. Just like Jesus, most Christian homeschooling parents are teaching their own, mentoring their own, spending quality time with their own, literally pouring their lives into their kids, instead of subcontracting virtual strangers to teach their precious children.
Jesus teaches us that truly effective discipling and training is done one-on-one, and it takes time and much sacrifice. Recent studies prove that Jesus' style of teaching is by far the most effective of any method, and the positive results are the proof. Dr. Brian Ray's research with thousands who were home-educated and now adults shows that less than 4 percent of homeschooled youth disown their faith by the time they reach their first year of college. This is literally the exact opposite of all the sobering research showing an approximate 90 percent rate of children from Christian families leaving the church by age 18. What a difference godly discipling makes!
This puts to rest the salt-and-light argument that many uninformed Christian parents use as an excuse to keep their kids in public schools. The overwhelming majority of children from Christian homes are being converted to an unbiblical worldview in the public school arena.
