I agree about the Christ centered marriage. THe truth is that when we try to follow God in life our outlooks change. I know that iv lived a life where i was a name sake christian for a very long time. THen i searched for God and found peace in life. Then i allowed life to get in the way of living a life for Christ. And surprise surprise my life turned into a life of sadness, depression, distrust and anger. Thankfully i tried to rededicate myself to living a life in relationship with God and have found peace again. Point being that i know what it means to feel angry all the time and hate people because you yourself are not happy in life. But when a man walks with Christ and picks up their cross everyday, the outlook on life does chance. The peace and love of God does indeed start to flow in us. So my hope is that if one day i am to marry , that ill be able to love my wife like a Godly man should. Like you said we arent perfect, but we can take each day as a challange to live like Jesus.
