How do we know free will is important for Christians?

The concept of free will is crucial for Christians as it emphasizes voluntary choice in responding to God. However, it's vital to distinguish between 'free will' with two words, which suggests complete autonomy, and 'freewill' as a single word, which indicates the spontaneity of our offerings to God while remaining firmly within the boundaries of His sovereignty. According to Scripture, our hearts must be made willing by Christ's redemptive power (Psalm 110), and thus, true willingness and the ability to choose life come from God. It acknowledges that while we are called to respond, it is God's grace that enables us to do so, creating a tension between God's sovereignty and human responsibility.
