“Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will.”
– Romans 12:2
Before we can ‘bring heaven down’ so that the will of God takes place on earth as it is in heaven (Matthew 6:9), we must know what the will of God is, and we must know what ‘takes place’ in heaven. These two things cannot be discovered by man. They can only be revealed to man by someone who has been to heaven and who has personal knowledge of God’s will. And when those matters are revealed, it rests upon each one of us to ‘prove to ourselves’ or ‘be able to know’ (Good News Translation) or ‘know how good and pleasing and perfect’ (New Living Translation) is the will of God.
Fortunately, there is one who personally knows both the Father and his perfect will. That is the Son of Man, Christ Jesus of Nazareth. About him is it written:
“No one has ever seen God, but the one and only Son, who is himself God and is in closest relationship with the Father, has made him known.”
– John 1:18
“No one has ever gone into heaven except the one who came from heaven—the Son of Man.”
– John 3:13
Man looks at life through a narrow veiled lens based on his limited understanding of the universe and the true personality of God the Father. He simply cannot know by his own reasoning the divine plan for mankind unless he examines the matter spiritually, through the mind of the only one who knows:
“The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit. The person with the Spirit makes judgments about all things, but such a person is not subject to merely human judgments, for, “Who has known the mind of the Lord so as to instruct him?” But we have the mind of Christ.”
– 1 Corinthians 2:14-16
So, the key to understanding the perfect will of God is to quit allowing ourselves to be fashioned after the thinking and the will of man, and then transform our thinking so that it conforms to the mind of Jesus Christ – the one who knows and revealed God’s perfect will.
