THE WAY & GOD'S INTENT
In addition to revealing that Jesus had been glorified and filling the Disciples with the Holy Spirit, the Day of Pentecost was the start of God's great intention.
Ephesians 3'10-12 says, all that was achieved by Jesus was:
"... to the intent that now the manifold wisdom of God
might be made known by Christ's Called-Out People
to the principalities and powers in the heavenly places,
according to the eternal purpose
which He accomplished in Christ Jesus our Lord".
Jesus had led the way. He manifested God's manifold wisdom. And the principalities and powers could not comprehend it (John 1'5).
Now, through the Lord's People living the Christ-Kingdom life, the enemy would be fully informed of God's wisdom!
