Absolutely! I never denied that. What I have explained through Scripture is that the adoption is future. It has not taken place yet. It is the future hope of the believer. Yes, we are sons now though the new birth, but our adoption is future. Remember, the adoption, as defined by Scripture, is the redemption of the body.
Eternal life also has a present and a future aspect too.
These things show that your conclusion about adoption does not follow from the premises. It’s your opinion.
