The first is obedience, which is what Peter speaks of in the verses above. Jesus continually tells us to be ready for His coming, which could happen at any time (cf. Mark 13:33-37) and to live in such a way that we are not ashamed of our behavior.
Patuloy na pinaaalalahanan tayo ni Hesus na maging handa sa Kanyang pagdating, na maaaring maganap anumang araw at oras mula ngayon (Markos 13:33-37) at mamuhay tayo sa isang paraan na hindi tayo magiging kahiya-hiya sa Kanya sa kanyang muling pagparito.
