Be kind with everybody but especially with your wife. Avoid considering whether her complaints are true or not. Care only about one thing: avoid making her sad, maintain peace in your home so that she would give you all her attention and you shall confess her all your sorrows so that you may find in her the consolation needed.
God resources to wonders in order to convince us only in special cases, and calls in a mystical way each one of us. Which means that our heart is lit by His light, we understand Him, we feel His call and we say “My Lord and God!” same as Thomas did when Jesus resurrected. We don’t touch, but only by increasing our spirit we get to see the unseen God.
