I am a bit confused on the meaning here. Since I am now single, my relationship is with the Lord, and I feel very protected. I had it backwards a few years back. I believed my spouse was suppose to protect our family and household. according to the Bible. as I understood it. " I am a southern country girl. I physically need no man to protect me ". Anyhow, I put my hope, trust and safety for my household in my spouse, instead of the Lord. My spouse did not see the need to protect or even erect a wall of protection around his own heart, for our marriage, or family. He is a man, and he failed. God will not fail. See before all this I did not have a personal relationship with the Lord, nor did I know I could have one. My church focused on the rules and doom and gloom. instead of love and grace. Because all that has happened. I now have my priorities straight. My protection comes from my Lord. Yes the Bible puts in on the man to be the head of a household, and he will be held accountable. However just like David, he is a man and will Fall. (not just pointing out you guys, for us women fail just as much) The point is, Protection comes from the Lord. All humans will fail you as some point.
Now if you are referring to trust, that is a whole nother ballgame.
