1 John 2:10

“He that loveth his brother, &c.] As such, and because he is his brother in Christ, and that cordially and sincerely, without hypocrisy and dissimulation, and by love serves him, both in things temporal and spiritual, and so observes the new, and yet old commandment, abideth in the light: it is a plain case, that such a man is in the light of grace, and continues in it; for though it is not his love to the brethren which is the cause of his light, of his being and continuing in it, for that is owing to the spirit of light and knowledge, but on the contrary, light is the cause of his love; yet it is an evidence of it, that by which it is known, as the cause is known by the effect; (see…”

He stumbles against himself, and against all things within and without; while he that loves his brother, has a free, disencumbered journey. 1 John 2:11”

“2:10 To cause others to stumble can also mean to ensnare or entrap them. The Greek word skandalon means a trap or a block in someone’s path. The Gnostics, who taught falsehood about Christ, were hindering people by ensnaring them in error and darkness. • living in the light: A godly life will help, not hinder, the faith of other Christians.”
