This is the concentrated teaching of a set of beliefs (political or religious) given to another person with the aim they will reject any other beliefs. Because those subject to such instruction are not encouraged to question or examine such teaching, it is often termed brainwashing.  By continual bombardment or giving a one-sided view of events even the mass media can be guilty of manipulating the thoughts and beliefs of their audience. 

The early believers were commended for not just blindly accepting what was taught to them, for it is recorded they diligently searched the Scriptures to confirm it was the truth (Act 17:11).

Such an encounter cannot be forced but only shared through loving actions. Society generally has no qualms about imposing its godless values on impressionable minds so parents can’t remain neutral in such an essential matter (Deut 4:9, 31:13).
