In the past you were in the darkness
Don't let anyone fool you with empty words, this is why God's punishment is coming against people who won't obey the word of God.
So, don't take part in any of the things that they do.
In the past you were in the darkness, but now the light has been shining on you, you need to keep this light on you as it comes from God Himself.
Test everything that is spoken to you, don't let the words stay with you without any substance to them.
Don't share in anything that does not come up to the truth, keep away from it, as they can pull you down.
Everything that has the light in it exposes what is not the truth, light makes everything clear.
"Get up, you sleeper! Rise from death! and, Christ will shine on you"
So we need to be very careful how we live, don't live like foolish people, live like wise people.
Try to understand what the Lord wants, always thank the Father for the things He gives to you.
He wants to give to you glorious gifts, but when we are not in His foot steps He can not give to us, as Christ's people we are to put ourselves under His authority.
Christ came so that we will not have stain or wrinkle or any such thing, instead He wants us to be holy and spotless
