In this world we have to deal with lose and separation.  First we have to leave the safety of our parents.  Then may have to leave the safety of a comfortable job.  Eventually when you have kids they will have to leave you to start lives of their own.  Through all of the separation and lose that you have to deal with on simple fact that you can hold on to is that Jesus Christ will never leave us or stop loving us.  This one of the key factors that keep me loving the beautiful wife that I have.  If Jesus can love me through all of my mess.  Than I feel it is my duty to share that level of commitment to my wife.  Really that is what marriage is all about committing to someone that you will never leave them and always love them just like God commits to us.

Romans 8:38New Living Translation (NLT)

³⁸ And I am convinced that nothing can ever separate us from God’s love. Neither death nor life, neither angels nor demons,^[a] neither our fears for today nor our worries about tomorrow—not even the powers of hell can separate us from God’s love.
