I know what you are going through because I am going through the same thing with my 2 sons.  I feel it is a test that we must go through, it is part of our purification.  I feel so sorry but just think that it is not far off when he will come and get us and think of the chagrin on your worldly wife's face because she will definitely know what happened and where you are and also what she will go through.  Don't bother to try to convince her anymore just talk with your little boy and keep the peace in your family so you will have a bit of peace yourself.  He knows what you are going through, pray to Him and leave it completely in His Hands, He will give you peace.    Andrea
