When we test all things, do we test ALL things?

So this past week our high school discipleship group studied 1st Thessalonians, the whole book! there's a lot in there, But I was blessed by the last bit of it as it spoke on testing ALL things in our lives.
1Th 5:21 "Test all things; hold fast what is good"

Hold fast what is good, this means to HOLD unto the good. Testing everything does not come easy for me, it's easy for me to judge, but there is a difference and I'm learning this. Judging is to look down and condemn something, testing is to see if it's truly true!
I need to learn to test ALL things in my life, it's hard to. It's convicting but without the Spirit we can't, unless we are testing everything we will not be firm in our faith. It's interesting that we read earlier on in that chapter not to quench the spirit. If we quench we won't be able to discern!
We need the spirit to test all things, is this truly of God? thats what we gotta ask ourselves.
Then the next part of that chapter comes in:
1Th 5:22 Abstain from every form of evil.

Are we abstain from EVERY form of evil? this is by testing we do, we need to be sanctified!
1Th 5:23 Now may the God of peace Himself sanctify you completely; and may your whole spirit, soul, and body be preserved blameless at the coming of our Lord Jesus Christ.

God of peace, he will cleanse us! We can't on our own, and we see this in the next and final verse!
1Th 5:24 He who calls you is faithful, who also will do it.

He is faithful to do that work, we can't in our flesh, we can't abstain from evil in our flesh without God, without the holy spirit! much to ponder.......
We must keep our eyes above!
