When we exchange the truth of God for a lie every area of our lives are impacted. In the context of Romans chapter 1 Paul specifically exposes how we are impacted in our thinking about our sexuality. When we exchange the truth of God for a lie every area of our lives becomes misguided. Our finances, our time, our work, our relationships (which include marriage and parenting) become skewed.
Even the way we “do church” can so subtly be derailed when we lose a correct picture of who God is and how He wants to guide us. The danger is when we think we have arrived in our understanding of God we set ourselves up to ride off in some “wrong direction”.
For us it must start with God and finish with God, lest we become compromised and start going through the motions.
