I've spent countless times worrying about offending people. One of the things I struggle with most about being a Christian, is that my beliefs offend people. Offending people goes totally against my personality. I'm always sensitive to how I affect people, especially if I like them. Maybe not so much if I don't. :) But the truth is, Christianity does offend, and I need to get over it. This scripture is powerful and what I try to always remember when I start to worry again about being offensive:
For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes.
And yes, one day at a time is right! Jesus said each day has enough problems so don't try to take on tomorrow. Ain't that right!
And you are right that He's not going to leave you. He never leaves his children. I find myself at times angry with him, wanting to run, having doubts. I always come to my senses eventually and not because of me, but because of Him. I hold on to this scripture because I know how frail and weak I am, and how much I'm prone to wonder away from Him.
26 My flesh and my heart may fail,
but God is the strength of my heart and my portion forever.
I can't put confidence in my own heart or my own flesh because I am well acquainted with how both can fail. But because his heart never fails, nothing of him fails, he is my portion forever.
One day your pain over losing your child, and all your pain, will heal, I know that for sure. Maybe not in this earthly life, but in the new heaven and earth, your pain will be no more. And the pain you feel now, as excruciating as it is, won't be able to be compared to what we will know then. It's going to be that good.
2 Corinthians 4:16
16So we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day. 17For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, 18as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.
It may seem I always tag a song at the end of my post. :) Just when I am responding to you. lol But this song is what I often listen too when I feel like everything I hold onto in this world is fading from me, when I feel like I've totally failed and there is no hope for me, or whatever else. I've put it on the Christian forum a couple of times, but you may have never heard it. I think it's beautiful.
