Relative to the exchanges Devona and I have had in the most recent posts below, it seems appropriate to proceed to the final point of the LCR document.
10. God desires that we put our trust in Him in all matters, also in His will and ability to provide for the children that He gives us (Exod. 23:20,26; Psalm 30:7; 37:25f.; Phil 4:13; 1 Pet. 5:7).
“Behold, I send an Angel before you to keep you in the way and to bring you into the place which I have prepared.
No one shall suffer miscarriage or be barren in your land; I will fulfill the number of your days.
LORD, by Your favor You have made my mountain stand strong;
You hid Your face, and I was troubled.
I have been young, and now am old;
Yet I have not seen the righteous forsaken,
Nor his descendants begging bread.
I can do all things through Christ who strengthens me.
1 Peter 5:7
...casting all your care upon Him, for He cares for you.
And, at the risk of being repetative, here I quote Luther again:
Although it is very easy to marry a wife, it is very difficult to support her along with the children and the household. Accordingly, no one notices this faith of Jacob. Indeed, many hate fertility in a wife for the sole reason that the offspring must be supported and brought up. For this is what they commonly say: “Why should I marry a wife when I am a pauper and a beggar? I would rather bear the burden of poverty alone and not load myself with misery and want.” But this blame is unjustly fastened on marriage and fruitfulness. Indeed, you are indicting your unbelief by distrusting God’s goodness, and you are bringing greater misery upon yourself by disparaging God’s blessing. For if you had trust in God’s grace and promises, you would undoubtedly be supported. But because you do not hope in the Lord, you will never prosper.
