Isaiah 26:3 New King James Version || You will keep him in perfect peace, whose mind is stayed on You, because he trusts in You.
Ephesians 2:14 New International Version || For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility
Mark 4:39 King James Version || And he arose, and rebuked the wind, and said unto the sea, Peace, be still. And the wind ceased, and there was a great calm.
God’s elect, the introduction of God into any situation is to bring peace and calmness to everything worrisome to His agenda in this life, which are humanity and the earth. In Genesis 1:1-2, after God created the heavens and the earth in verse 1, confusion and darkness had come upon the universe again, and then His (God) Spirit which is the Holy Ghost/Spirit comes to brood or move over the creation of God and then new creation begins with the word of God – that is the personality of Peace in operation.
In Mark 4, Christ Jesus was asleep on the boat while the winds were becoming worrisome, He woke up and told the storm to be peaceful and still. Now, He (Jesus) has become our peace in Ephesians 2:14 and He says by the Prophet Isaiah 26:3 that He shall keep Him in perfect peace whose heart/mind is stayed on Him.
Our God is a God of peace, unless He needs to bring a fight or a war on the enemies of His children to still give them peace or calmness.
God’s elect whatever confusion you might be going through just have your mind stayed on the Lord Jesus and He shall keep you in Perfect Peace.
