Then you must believe that the Jews who lived under the law were saved apart from works because this is what He told those people:
"Jesus said to her, “I am the resurrection and the life. The one who believes in me will live, even though they die; and whoever lives by believing in me will never die" (Jn.11:25-26).
"For my Father’s will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise them up at the last day" (Jn.6:40).
"Very truly I tell you, whoever hears my word and believes him who sent me has eternal life and will not be judged but has crossed over from death to life" (Jn.5:24).
Clete, are you "pretty sure" that the Lord Jesus meant what He said when He told the Jews who lived under the law that those of them who "believed" received those spiritual blessings?
And are you "pretty sure" that "whoever" believes has eternal life and will not perish?:
"For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life" (Jn.3:16).
