You must be in fellowship prior to your Bible study, so that the spiritual information you receive can become a source, of blessing to your soul and produce spiritual growth.
23 Now [de] it was [grapho] not [ou] written [grapho] for his sake [dia][autos] alone [monon], that [hoti] it was imputed [logizomai]
to him [autos];KJV-Interlinear
23 But the
words “it was counted to him” were not written for his sake alone, ESV
And Paul makes it very clear that this faith of Abrahams, and the resulting salvation, was not just for him, but is the pattern by which we all have been saved.
Adam was saved in this manner, and every person in every generation who has believed in Christ, and every person in the future who will believe in Christ, will be saved in the same fashion.
And all who believe, are credited with Gods righteousness.
As far as that goes, there are many blessings that we receive at the moment of our salvation, but for now, if you have believed in Christ, then at that first moment of your faith, you received and you now possess, Gods righteousness by virtue of your faith in Christ.
That is imputed into you and is a permanent part of your essence. You cannot get rid of it. No one can take it from you. You cannot lose it.
Once saved, always saved. You cannot un-save yourself.
