Many look for external beauty but I believe that what is inside matters more. God's plan is to bless each us (Jeremiah. 29:11) . His plan is to bless you with a mate that is capable of supporting His plans for your life. Choosing a mate of God's design will serve as a catalyst for you to reach your Divine Destiny in Christ Jesus. Many times people subconsciously search for personalities that are on their wavelength and sometimes it takes a while for people to realize they don't fit. If you can discern incompatibility early, it will save a lot of heartache. As George Eliot stated in his quote about friendship (and I have learned it to be true) , "keep what is worth keeping, and then with the breath of kindness blow the rest away. "
