I agree God chose us from the beginning. When you fell in love with your wife for the first time...you chose her in your heart. scriipture tells us that God loved us first. Your wife made the choice to love you back...you may not have had the same results if you forced her against her will.
As far as not "believing" whether a refractometer makes any difference in giving you the proof you need. I can only say, that using one and taking note of high or low brix and then making note of the difference you feel as you experiment with them is the only way your lack of faith in what I say or Ml says or anyone else will convince you. Perhaps God will give you a dream about this subject and then you may reconsider. The fact that you choose to not try tells me something about you. You want God to handle everything as though you have no responsibilies at all. It's like you are looking for heavenly welfare.
My husband is head of our household. He guides me and I listen but he does expect me to participate in our marriage. I have a part to play in this thing we call life.
Listen, I have enjoyed our discussion and praising God with song very much. We are both believers and even if we disagree on some things, we both love the Lord. How you choose to lead your families life on this earth is your business. If you want help with physical healing, God can either heal you instantly or can point you in a direction to find it. I wish you the best.
