The word of God is like oxygen to us. We cannot survive without that.
in the beginning was the word, and the word was with God and the Word was God. John 1:1
The word of God is like a mirror. We can use it to reflect our current state. Just like how a mirror shows us what is good and what needs to be fixed. The word of the Lord does the same for our souls.
But knowledge of the word is not enough, we need to put it into action.
You can resist the devil only by the word of God. Even Jesus used the word to resist Satan. With persistent meditation of the word of God, morning and evening, we need to fill our minds and hearts with the word of God.
That person is like a tree planted by streams of water, which yields its fruit in season and whose leaf does not wither— whatever they do prospers. Psalms 1:3
Decide to prioritize the word of God. Before we do anything, we need to be at the feet of God. Set our life right with God.
Great peace have those who love your law, and nothing can make them stumble. Psalms 119:165
If your law had not been my delight, I would have perished in my affliction. Psalms 119:92
Delight in the word of God, it will not let you perish in any problem/situation that you are facing.
