And then there is the actual Word (as opposed to opinion).
Hebrews 10
26 For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries. 28 Anyone who has rejected Moses’ law dies without mercy on
the testimony of two or three witnesses. 29 Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot,
counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace? 30 For we know Him who said, “Vengeance is Mine, I will repay,” [
g]says the Lord. And again, “
The Lord will judge His people.” 31 It is a fearful thing to fall into the hands of the living God.
Hebrews 6
4 For
it is impossible for those
who were once enlightened, and have
tasted the heavenly gift, and have become
partakers of the Holy Spirit, 5 and have
tasted the good word of God and the
powers of the age to come, 6
if they fall away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put
Him to an open shame. 7 For the earth which drinks in the rain that often comes upon it, and bears herbs useful for those by whom it is cultivated, receives blessing from God; 8 but if it bears thorns and briers,
it is rejected and near to being cursed,
whose end is to be burned.
The actual Word of God, which is plain and straightforward to understand, carries more weight than mere opinion or assertion.
