How can we help a teenage brother living in a European country who accompanies girls, and whose family fears he will become alienated from religion if they pressure him, in order to protect him from falling into grave sins?

Parents must instill principles of goodness in a child early, because education in youth is like engraving on stone. If he grows up and enters adolescence in an environment where good companionship is scarce, it becomes difficult to guide him. The matter requires patience, struggle, supplication for him, continuous advice and education, finding good companionship to help him commit, and keeping him away from bad friends who negatively affect his behavior and morals.
