Submit to God. How to submit? Why?

James 4:7

Therefore submit to God. Resist the devil and he will flee from you.

"In all the New Testament incidences where the word submit occurs, the word is translated from the Greek word hupotasso. The hupo means "under" and the tasso means "to arrange." This word and a root of it are also translated by the words subject and subjection. The word's full meaning is "to obey, put under, be subject to, submit oneself unto, put in subjection under or be under obedience or obedient to."

1 Peter 5:5-7

Likewise you younger people, submit yourselves to your elders. Yes, all of you be submissive to one another, and be clothed with humility, for “God resists the proud, But gives grace to the humble.”
Therefore humble yourselves under the mighty hand of God, that He may exalt you in due time, casting all your care upon Him, for He cares for you.

"The theme here is one of humility. One cannot submit to God without humility. Obedience requires us to humble ourselves to surrender to the authority of another, and we are told that God resists pride—the opposite of humility—and the arrogance that fosters that pride."

"as born-again believers we daily make a choice to submit ourselves to God for the work that the Holy Spirit does in us to "conform us to the image of Christ." God will use the situations of our lives to bring us the opportunity to submit to Him."

Romans 8:28-29

And we know that all things work together for good to those who love God, to those who are the called according to His purpose. For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren.

"We have to choose to submit to God for the process of learning in order to grow spiritually. It is a process begun at salvation and ongoing with each and every choice that we make to submit ourselves to God. This process will continue until the Lord comes again or He calls us home.
The wonderful thing about this is that, as the Apostle Paul so aptly states:"

2 Corinthians 3:18

But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the LORD.

"God does not require us to submit because He is a tyrant, but because He is a loving Father and He knows what is best for us. The blessings and peace that we gain from humbly surrendering and submitting ourselves to Him daily are a gift of grace that nothing in this world can compare to."
