Ephesians 3:5, which reads:
This was not made known to people in other generations as it is now revealed to his holy apostles and prophets by the Spirit:
Friend, God never intends for us to live our lives having only a head knowledge that He loves ALL MEN. Such knowledge alone will confuse any theology we have on God’s love as we will desperately try to reconcile how the worst sinners could possibly be loved by God. And, how God could love even us.
BUT, God in His Grace and Mercy has revealed this to us through the apostles and prophets, so if you are grappling with God’s love open your Bibles to read and to reread and the meditate upon the stories showing God’s love for mankind
Such revelation can be likened to being drenched with a summer rainstorm.
Just as you did not manufacture the Summer rainstorm, you can not intellectualize God’s love; but, just as you CAN move into that rainstorm, you can move into God’s love
So, friend, regardless of where you are in your faith walk, move more into the revelation of God’s love
