(Matthew 28:18-20) And Jesus approached and spoke to them, saying: “All authority has been given me in heaven and on the earth. Go therefore and make disciples of people of all the nations, baptizing them in the name of the Father and of the Son and of the holy spirit, teaching them to observe all the things I have commanded you. And, look! I am with you all the days until the conclusion of the system of things.”
please note the admonition to go, a Christian command to teach others, incumbent upon Christian disciples by Christ, ask yourself the question, when was the first or last time a Christian came to your home, after the manner of the apostles, to teach you about Gods Kingdom?
Notice the importance Christ gives to teaching others,
(John 17:3)This means everlasting life, their taking in knowledge of you, the only true God, and of the one whom you sent forth, Jesus Christ.
Yes indeed the disseminating of Biblical knowledge means everlasting life to those who partake, when was the last time someone came to your home to disseminate this knowledge to you?
The Apostles of Christ realised the importance of this also,
(Acts 5:42) And every day in the temple and from house to house they continued without letup teaching and declaring the good news about the Christ, Jesus.
Indeed ask yourself the question, when was the last time a professed Christian came to teach you, after the manner of the apostles, in obedience to the command of Christ knowing that it means everlasting life to those who are willing to take such knowledge in, for it seems that their exist Christians who are willing only to constantly criticise others for their faith, yet they seem unwilling to lift a finger to teach others, despite the importance that Christ placed upon the work.
Excuses so far proffered, its none of your business, not all are teachers? Was Christ's command to teach not incumbent upon all Christians,was the apostolic example not to go to people, wherever they may be found, in homes, in the temples, in the market place for a public witness? Indeed, lets us here ask why they have not done so, yet seem able to point out the faults of others who are willingly doing this work in obedience to Christ command.
