Spirit -> Flesh = Foolish

I must say, one of the most perplexing sections of scripture is the historical account of Jephthah's foolish vow found in Judges 11:29-40 (Check it out for yourself). The vow was foolish. It was not commanded by God nor was it commanded to be upheld by God. Jephthah never turned to God in the midst of it, and though I have read commentaries which write it off, the Bible clearly says he went through with his vow. The Bible did not command it, God did not command it, Jephthah simply did something foolish. Jephthah's vow was tragic and foolish because even though he had begun in the Spirit (Judges 11:29), he tried to sway God and secure a victory by his fleshly efforts (Judges 11:30), an act that was unnecessary which in the end cost him his family! Paul spoke of this exact foolishness to the Church in Galatia saying, "Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh? We do the same thing when we turn from our simple faith in God and try to perfect through our flesh a work that can only be done through the Spirit of God! Have you taken control of your own Christianity and placed the burden on yourself and your religion? Repent and relent! Place your confidence in Christ and rely in the power of His Spirit! Don't be foolish like Jephthah!
