The Bible is called the Sword of the Spirit, and the Word of God. But it is also called "a two-edged sword". Which means that it cuts two ways:
1. For those who humble themselves before God and believe Him ---> it opens up spiritual truths like a scalpel wielded by a surgeon.
2. For those who seek to oppose God and refuse to believe Him ----> it cuts them off from further light and blinds them to God's truth.
Yes...and this works for believers who seek to control their own walks by leaning on their own understanding. Cut off from..."further light"...
Matthew 23:37
37 O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not!
The killings and stonings today are in the hearts of the enemies of the cross...who lean on their own apprehension of dogmatic ideologies and have no love in them.
