The Secret.

# How much influence does the spirit (Heaven) have over the body (Earth)?

If every young man or woman pay utmost attention to the answer to this question, and seek out early the truth behind it, they (we) will be very strong and do exploits. Everything that is MADE or seen was first CREATED from the unseen. Therefore, things that are seen or made are temporal and subject to change, but things not seen or created are NOT subject to change or destruction, for they are eternal (2Cor 4:18). 

# The eternal, heaven, unseen, or spirit RULES OVER the temporal, earth, physical, or body.

"GOD IS A SPIRIT: and they that worship him must worship him in spirit and in truth." (John 4:24)... for the spirit is the life of the body. God was IN Christ RECONCILING the world to Himself; LEADING Christ about; SHOWING Christ all what to do and say; HEALING the sick and setting the oppressed free; Etc. God the Holy Spirit did ALL these through Christ, His Body (Heb 10:5). 

# You can't give up all you have for this precious truth and still have lack of any good thing in life. 

No wonder Christ said in Mat 6:33-34 to SEEK FIRST WITHOUT worry for tomorrow His Spirit (the Father and His Kingdom) and His Righteousness in order to live His "far above" kind of life. To the young men and women (Acts 2:17), it's NEVER a foolish decision to seek out the Truth early in life and not later. First find Christ and KNOW HIM personally and then build (or put) your Family, Career, Desires, Retirement?!, Policies and Politics, etc on Him. The enemy will surely come like a flood, but it's only the Spirit of Christ, that shall lift up a standard against him (Isa 59:19).
