Promise 86 Gen. 38:10

Gen. 38:10 - "But what he (Onan) did was displeasing in the sight of the Lord; so He took his life also." I'm not sure what was worse what Onan did, to rebel against what his father asked him to do or to waste the seed that would give life. I think both are equally bad. Onan dishonored both his earthly father and his heavenly one. It's God's choice whether to give life or take it. Onan purposefully denied Tamar children because he was selfish, this also hindered God's promise to Jacob that his descendants would be many. Anytime we knowingly fight against what God has promised and go against His plan there are consequences. God is not One you want to mess with and knowingly make mad. Onan withheld life and so did God by taking his.
