For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord. (Romans 8:38-39 ESV)
I've made lots of mistakes in life. Hopefully, I make fewer as time goes on. Partially, because I just don't have the interest or ability to try different things as I age. But, mostly because as I walk by the Spirit I do not gratify the desires of the flesh, for these are opposed to each other (Galatians 5:16).
Thank God for the Spirit He has freely given me to understand even the deep things of God (1 Corinthians 2:10-12)! Even though I may wander away from Him, or even push Him away, He is always ready, willing, and able to take me back in His loving arms.
To turn back to Him takes genuine honesty and sincere humility on my part. But, He is always ready to forgive me and cleanse me from all unrighteousness, so that I may get back into fellowship with him. (1 John 1:9, 1:6-7) And that's a joyful thing!
There is a unique kind of intimacy with Him that has no worldly equal. Scripture calls it fellowship, but it is not simply sharing a meal or going bowling with the guys.* It transforms the desires of my heart to delight in Him (Psalm 37:4).
* Careful: neither is confessing the same as getting back into fellowship. Rather, with humility, continue to diligently seek Him.
I can see now why he uses the analogy of an ideal marriage to help us understand the possibility of this relationship (Ephesians 5:31-32). Most of all, I'm so happy to know that nothing will separate me from this love.
Nothing at all.
