Stumbling Block or Building Block?

"Then He said to the disciples, 'It is impossible that no offenses (stumbling blocks) should come, but woe to him through whom they do come!  It would be better for him if a millstone were hung around his neck, and he were thrown into the sea, than that he should offend one of these little ones.' "(cause one of these little ones to stumble) (Luke 17:1,2)

" 'Behold, I lay in Zion a chief cornerstone, elect, precious, and he who believes on Him will by no means be put to shame.' Therefore, to you who believe, He is precious; but to those who are disobedient, 'The stone that the builders rejected has become the chief cornerstone', and 'a stone of stumbling and a rock of offense'. They stumble, being disobedient to the word, to which they also were appointed." (1 Peter 1:6-8) Their stumbling causes others to stumble. They "transgress (or go ahead) and do not abide in the doctrine of Christ (they do not) have God. He who abides in the doctrine of Christ has both the Father and the Son". (2 John v.9) 

Why would it be better for the offender to physically die than to cause one of these little ones to stumble? It derails the development of a young believer. Their offense is a direct rejection of the chief cornerstone; it is disobedience "to the word, to which they ALSO were appointed". Any builder must be devoted to obedience to the word.

"Take heed to yourselves. If your brother sins (transgressing the doctrine of Christ), rebuke him; and if he repents, forgive him. And if he sins against you seven times in a day, and seven times in a day returns saying, 'I repent,' you shall forgive him." (Luke 17:3,4) Remember, after Jesus death, resurrection, and taking away to the Father, the original disciples, other than Judas, were the builders. Jesus taught them and His words teach us now.
