The Kingdom of God is about, God, teaching us His ways, so that we can walk in His paths. The restoration of all things is firstly each one of us coming back to the place in Him as before the fall. It has everything to do with the Father's heart being restored to His children and in turn His childrens hearts return to Him.
When you agree to disagree you either don't know the truth or you are compromising the truth. When you hear and see and then compromise what you hear and see you have a product of fallen truth, truth needs to be held on to and stood upon, eventually it will come through and will be standing when all else has fallen. https://biblehub.com/isaiah/59-14.htm
Truth is what is seen and heard with spiritual eyes and ears.
God reveals Truth to the heart, knowledge is not enough, good works doesn't do it. Faith must be learnt and used to access the Life giving Truth that God freely gives
There is a rest for those of the household of faith. One can only be carefree if God has your cares. Trusting in God all the time removes one from their own cares. Faith does have an ignition point which is by the words of your mouth which is the words of faith and having also a mind set that your cares are cast to him. Those outside carry the load of thier own cares and they also are in the position of being responsible for thier own cares, which really is not a safe place to be. The thinking of the world is different from the thinking of the Kingdom of God, those who act as one in the Kingdom have God who keeps His Word. Jesus said my yoke is easy and my burden is light, with saying this He says come to me, the way we come to Him is only by faith. He promises to those that come to Him, He will give rest. If we come to Him all the time we will always be in rest.
A friend of God There are a few that God calls them His friends, but what about the others? There is likely more that He calls His servants and then what about them and the others? If He is not calling you His friend then I imagine He won't speak to you like He is your friend, If He is not your friend or you are not His friend how would you speak together like friends. It is also the same in human relationships, one can only speak as a friend to one when they really are friends. When one is a friend of God, they can introduce God to another to be friends with Him also, if one is just a servant then they can only introduce God to one as a servant. When one is friends with God how can they be friends with those that are not whether they be servants or whether they be pagans. But a friend of God can give invitations, but it is up to those that receive the invitation to either come or not.
