Everyone who is of the truth hears My voice.
John 18:37 NKJV
For since the creation of the world God's invisible qualities--his eternal power and divine nature--have been clearly seen, being understood from what has been made, so that men are without excuse.
The lamp of the LORD searches the spirit of man; it searches his inmost being.
In the past, God spoke to our forefathers through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son.
