Irrational thought is disordered thought. God Himself orders your thought because your thought was created by Him. Guilt feelings are always a sign that you do not know this. They also show that you believe you can think apart from God, and want to. Every disordered thought is attended by guilt at its inception, and maintained by guilt in its continuance. Guilt is inescapable by those who believe they order their own thoughts, and must therefore obey their dictates. This makes them feel responsible for their errors without recognizing that, by accepting this responsibility, they are reacting irresponsibly. If the sole responsibility of the miracle worker is to accept the Atonement for himself, and I assure you that it is, then the responsibility for what is atoned for cannot be yours. The dilemma cannot be resolved except by accepting the solution of undoing. You would be responsible for the effects of all your wrong thinking if it could not be undone. The purpose of the Atonement is to save the past in purified form only. If you accept the remedy for disordered thought, a remedy whose efficacy is beyond doubt, how can its symptoms remain? T-5.V.7:1-12

When we think in terms of the world of the ego it is irrational because the world of the ego is an illusion, a world we made up. We want to believe the world of the ego is real even though it separates us from the Kingdom of God which is always there whether we are aware of it or not. The disordered thoughts of the world of the ego make us feel guilty about separating ourselves from the Kingdom of God. When things go wrong in the world of the ego we think we have made a mistake and try to correct it but this attempt at correction of something that is disordered to begin with is misguided because the correction of things in the world of the ego is not where the problem lies. The solution lies in shifting our minds from the world of the ego to the Kingdom of God, from conditional love to unconditional love. When we shift to unconditional love we have chosen the Atonement and the guilt over separated thinking, which was never real but only a dream, disappears.
In Unitarian Universalism we join together to affirm and promote the free and responsible search for truth and meaning which is to be found in the Kingdom of God not in the world of the ego.
Today, it is suggested that we refocus from the conditional love of the world of the ego to the unconditional love of the Kingdom of God.
