Isaiah 26:3 You will keep him in perfect peace, whose mind is stayed on You, because he trusts in You.
John 14:27 Peace I leave you, My peace I give you; not as the world gives, do I give to you. Do not let your hearts be troubled, nor fearful.
Perfect peace is probably the strongest indicator given to us by the Father that we are operating in His glory at any given moment, but another sure indicator are the words that we consistently speak. There can be many evidences of His glory manifesting in our lives, but our words are a huge one! They are either a dead give-away of walking in the old nature, or a living give-away of walking in the new nature. On a very simple level is optimism verses pessimism, positivity verses negativity. A person speaking positively doesn’t mean that he is in Christ, but it is an indicator on a very low level. What words are said are even more important and more of indicator.
A Christian who speaks negatively at length is still operating out of the old nature. What he says may be true, but they aren’t words to restore. Reconciling someone to the Father (and I’m not just talking about salvation) must bring that person all the way up to where Christ is at the Father’s right hand.
It can’t stop and cry forever at the cross, and it can’t condemn others with words that continually remind them they messed up or got it wrong. While the cross is one of the steps or way-points, and a very important one, even a daily one, it must be coupled with the rising from the dead to new life, and then ascending to the right hand of the Father where we overcome. That happens now as we live. Not knowing this causes people to live defeated lives and in condemnation when we don’t have to. We must go full circle to the Father to overcome anything. Jesus said,
“Most assuredly, I say to you, he who believes in Me, the works that I do he will do also; and greater works than these he will do, because I go to My Father.” (John 14:12)
“Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father except through Me.” (John 14:6)
“I came forth from the Father and have come into the world. Again, I leave the world and go to the Father.” (John 16:28)
