However, I would like to share with you a more excellent way to have God's protection. In order to do so, I need to mention circumcision.
In the Old Testament, physical circumcision was required of God's people. Physical circumcision is a procedure that initially leaves a man rather vulnerable in the natural. Circumcision was used in the Old Testament as a Covenant with God, declaring that their trust was in Him alone and not in themselves.
In the New Testament, specifically Romans 2:29, Paul talks about having our hearts circumcised. What does that mean? I believe it has to do with having our own self-protection stripped away. David in the OT had the right idea when he refused to wear Saul's armor, leaving him vulnerable in the natural and he put his trust in God alone to defeat Goliath.
Another thing to consider is that the devil is God's devil. The devil is not able to do anything that God doesn't allow. Sometimes God will allow the devil to humble a person. I am currently reading the book of Samuel. In Samuel 18:10, it says that, "an evil spirit from God rushed upon Saul." In the book of Job, God allowed Satan to test Job. In the New Testament, specifically in 1 Corinthians 5:5, Paul talks about handing a person over to Satan for the "destruction of the flesh, so that his spirit may be saved."
God's heart is ultimately for us to be protected and it can happen sovereignly but it is usually a process that does not happen overnight. Gaining God's protection sometimes can take a lifetime of us learning to abide in Christ as we yield and walk with God in humility. This process, is accelerated through trials, where we learn to let go of self-protection and find protection under the shelter of God's wings (Psalm 91). As we learn to find shelter and protection, tucked away under God's wing, we become invisible to the enemy and we become clothed with the armor of God mentioned in Ephesians 6. The armor of God; helmet of salvation, breastplate of righteousness, belt of truth, shield of faith, shoes of the Gospel is ALL Christ! It is being clothed with Christ!
That is our goal and happens as we learn to abide. John 15:4 says, "Abide in me as I abide in you." The way to abide in Christ is to let go of everything that hinders us; our self-protection, our fear, our sadness, our idols, etc. and learn to rest.
Exodus 14:14 - The Lord will fight for you and you have only to be still.
