"In any moment of decision, the best thing you can do is the right thing, the next best thing is the wrong thing, and the worst thing you can do is nothing."
-Theodore Roosevelt (born in New York City on October 27, 1858)
...Frankly, this sounds a LOT like what Paul was trying to communicate to the church in Philippi - "Remember that if a man knows what is right and fails to do it, his failure is a real sin." (Philippians 4:17, Phillips)
Do the next thing. Sometimes it might not be clear, but we can be grateful for the Lamp that lights our path even in the darkest of nights. ... but if we freeze in the darkness, there is no way we can do anything. There is something that needs to be done, even if it is simple as talking with - n.b. encouraging, confronting, praying with,... - a Christ-sibling.
... and if you find you cannot move, turn to the One who holds everything, for "in Him we live, and move, and have our being" (Acts 17:28).
He is the only one who can move us forward, and His is the standard we need to live by, else how would we be able to judge right from wrong? Praise God for His Word, which is the best guidebook for all our choices!
