3:2 `Wake up, and strengthen the things that remain, which were about to die; for I have not found your deeds completed in the sight of My God.

WAKE UP

Be watchful! A few at Sardis still knew of the real God, the real Son, and the real Holy Spirit but they had been suppressed so long by "ritual" (worthless religion) that they needed to wake up. The same is true for ALL churches today.....WAKE UP!

and STRENGTHEN the things that remain, which were about to die;

for I have not found your DEEDS completed 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?
