'Put on' in the Bible

But the spiritual man [the spiritually mature Christian] judges all things [questions, examines and applies what the Holy Spirit reveals], yet is himself judged by no one [the unbeliever cannot judge and understand the believer’s spiritual nature].

But [as for me personally] it matters very little to me that I may be judged by you or any human court [on this point]; in fact, I do not even judge myself.

For this perishable [part of us] must put on the imperishable [nature], and this mortal [part of us that is capable of dying] must put on immortality [which is freedom from death].
