In Genesis 18, the Lord was about to destroy Sodom and Gomorrah. Verse 17 says, “…Shall I hide from Abraham what I am doing?” In John 15:14 Jesus gave His criteria of friendship. It says, “You are My friends if you do whatever I command you.”
The privilege of that friendship for us is in verse 15. It says, “No longer do I call you servants, for a servant does not know what his master is doing; but I have called you friends, for all things that I heard from My Father I have made known to You.”
I love 1 Corinthians 2:10 in the Amplified. It says what He has unveiled and revealed to us. “…for the Holy Spirit searches diligently, exploring and examining everything, even sounding the profound and bottomless things of God (the divine counsels and things hidden and beyond man’s scrutiny).”
