'Persuaded' in the Bible

For I am convinced [and continue to be convinced—beyond any doubt] that neither death, nor life, nor angels, nor principalities, nor things present and threatening, nor things to come, nor powers,

I know and am convinced [as one] in the Lord Jesus that nothing is unclean [ritually defiled, and unholy] in itself; but [nonetheless] it is unclean to anyone who thinks it is unclean.
