Prophet said, "Yes, birth control is opposed to faith, and apparently angers God greatly."
This has been my view throughout my married life. My wife and I always trusted God to give us those children that He desired we have, and not have here on earth, as some have died.
I do not think I could prove from the Bible that birth control is sin in any or all its forms, but in light of scriptures such as Gen 38, which gives one great pause, I have always believe that it is not pleasing to the LORD to decide whether or not to have children.
Lo, children are an heritage of the Lord,.... As all success, safety, and the blessings of life, depend on the providence of God; so this very great blessing is a gift of his; having children, and those good ones, as the Targum interprets it; for of such only can it be understood: so, in a spiritual sense, the children of Christ, the antitypical Solomon, are the gifts of his heavenly Father to him; his portion and inheritance, and a goodly heritage he esteems them;
and the fruit of the womb is his reward; "fruit"

is the same with "children" in the preceding clause; see Luk 1:42; a reward he gives to good men, not of debt, but of grace; the Targum,
"a reward of good works:''
so regenerate persons are a reward to Christ, of his sufferings and death, Isa 53:10.
