3:2 Be alert, and strengthen the things that are left which are about to die. I have found that what you are doing has not been completed in the sight of my God.

Be alert,

Be alert, and

strengthen the things that are left which are about to die.

for I have found your deeds unfinished in the sight of my God.

The previous churches at least had good comments about their deeds. The Sardis church started things but didn't finish them.

What deeds, then, are good and completeable?

LOVE -Thou shalt LOVE the Lord thy God with all thy might, soul, and spirit. Reread the LOVE chapter.
FAITHFULNESS-All seven churches have a blessing for the faithful OVERCOMERS! Find them.
PERSEVERANCE-See the churches at Ephesus and Smyrna.
KEEP HIS WORD-I have treasured Your word in my heart, so that I may not sin (and hence be DEAD) against You. (Psalm 119:9-11-16).
NOT DENY HIS NAME-Peter did before the cock crowed (Matthew 26:31-35,69-75)...how about us?
