Passage
for these things being to you and abounding, do make <FI>you<Fi> neither inert nor unfruitful in regard to the acknowledging of our Lord Jesus Christ,
for these things being to you and abounding, do make <FI>you<Fi> neither inert nor unfruitful in regard to the acknowledging of our Lord Jesus Christ,
2 Peter 1:6 and in the knowledge the temperance, and in the temperance the endurance, and in the endurance the piety,
2 Peter 1:7 and in the piety the brotherly kindness, and in the brotherly kindness the love;
2 Peter 1:8 for these things being to you and abounding, do make <FI>you<Fi> neither inert nor unfruitful in regard to the acknowledging of our Lord Jesus Christ,
2 Peter 1:9 for he with whom these things are not present is blind, dim-sighted, having become forgetful of the cleansing of his old sins;
2 Peter 1:10 wherefore, the rather, brethren, be diligent to make stedfast your calling and choice, for these things doing, ye may never stumble,
The verse centers on "things", "abounding", "make", "neither", "inert", "unfruitful", "regard", and "acknowledging". It is saying that the verse draws attention to "things" and "abounding", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 7's "and in the piety the brotherly kindness..." into verse 9's "for he with whom these things are...", so "things" and "abounding" belong inside that flow. In 2 Peter context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "things" and "abounding" with trust shaped by these words, not by a vague optimism outside the passage.
