“Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God” 1 Corinthians 2:12.
It is difficult to understand the Word of God without the help of the Holy Spirit. Our logical minds are too weak for comprehending the purposes and plan of the Almighty. That’s why Jesus promised not to leave us alone, but to send us the Holy Ghost to lead us into all truth. And He fulfilled the promise. On the day of the Pentecost the Comforter came and He is there to stay with us till the day we return to our eternal home.
