There's a lot of knocking today but are we listening for the voice of God

Revelation 3:20

20 Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.

There's a lot of knocking today but are we listening for the voice of Jesus. If we just open door without hearing the voice the voice of Jesus then anything can come in. It could be 7 more worse than the first. Be careful what we allow in know the voice of God and another you won't open the door for
