I absolutly agree that we should not be unequally yoked with unbelievers. God has a plan for our lives, and we as christians should most definately leave our life in Gods hands... Let him guide you and lead you, Seek God first... and all the rest will be set in order for you - If you truley believe.
I was in a relationship with a person for 8years who was raised as a christian by his grandmother but did not activley seek God in his day to day life. Whenever I was going through a struggle or some harship and just wanted to get down on my knees and pray for an hour or so about my trial, my partner would think I was being overly dramatic (his family even thought the same). Its can become extreamly difficult leading the life in Christ that you truley desire, if the enemy decides to use you spouse to divert you attentions.
Hence my reason for being on a website dedicated to "Christians" God has given man his own free will, so he will not force us into the direction that we need to be in, but as I said above, if you seek through him... You will find. Your soulmate should be like minded and have the same spritual desire as you, so that when you ultimatly become one through marriage you have the same hopes, dreams and aspirations for yourselfs, the future, and your childrens future. (just my opinion)
Furthermore, you can seek God together, have fellowship with your spouse, and pray together, and read your bible together... (this kind of fellowship cannot be brought) we all live one life for a purpose, for we are but dust of the ground, and it is our souls that will go on to live for all eternity. Will we choose heaven for ourselves and leave our spouse to their own devices?
