“Eido” is the Greek word translated “know” in 1 Corinthians 2:12. It also means “become aware.” It’s the same word used in Romans 8:28: “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.” In other words, you need to become aware of your lot in Christ.
It’s such an awareness that brings about assurance and rest in your spirit that makes you certain that no matter what happens, you can never be defeated, hence would not be moved. This is why Paul said in Philippians 4:6-7, “Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.”
“Peace” as used above is similar to the Hebrew word “shalom,” meaning “peace with prosperity.” In other words, when you become aware (“eido”), peace (“shalom”) is ministered to you by God’s Spirit! No matter the oppositions, challenges, or contrary winds that may come your way, you’re at peace and full of rest. It has become part of the scope of your knowledge that nothing in this life is set against you; thus, you can never be disadvantaged. You just laugh your way victoriously through life because you “know” that everything is designed to only work out for your good. Hallelujah!
