"And the Lord said unto Abram, after that Lot was separated from him..."
There may be someone close to you who is muffling the voice of God in your life. This person (or persons) may not be intentionally malicious (or may be), but their presence is distracting. When God seeks to draw us to Himself, it seems they are always there to bring us back down to earth. This individual may be someone in your own family, as in Abraham's case. This is unfortunate. Or it may be someone who has come to seem like family. One way or the other, until you are separated from him or her or them, either geographically or emotionally, the clear voice of God will seem garbled to you.
This thought lies too close to a nerve for much elaboration, I think; so I will simply leave it to the Holy Spirit to apply as He sees fit.
