We may think that faith and belief are wishy-washing things that can change with our mood or socio-economic situation. But the way the Bible uses those concepts, the clearer translation may be “trust” or “dependable.” We trust in God’s words, find the promises of Heaven dependable.
But the flip side of that is, are we trustworthy? Are we dependable? Are our desires, lives and resources following after Heaven’s instructions? Or are they wandering back and forth between God’s rules and the Zeitgeist, the Spirit of the Age, what’s trendy and popular.
Those questions are behind the instructions about marriage and adultery in the Torah passage כי תצא Ki Tetze (“when you go forth,” Deut. 21:10-25:19).
