'Convinced' in the Bible

{remembering the} sincere faith in you, which lived first in your grandmother Lois and your mother Eunice, and I am convinced that [is] in you also,

for which reason also I suffer these [things]. But [I am] not ashamed, because I know in whom I have believed, and I am convinced that he is able to guard [what] I have entrusted until that day.

But you continue in [the things] which you have learned and are convinced [of], [because you] know from whom you learned [them],
