Salvation is guaranteed the moment one believes Jesus for it. But becoming a Christian never guarantees that we’ll live like one. Spiritual maturity is not automatic. It requires diligent engagement with Jesus if we hope to change and grow. In the third of five warnings in Hebrews, the author reminds us that if we fail to mature and if we loosen our grip on Jesus, it’s only a matter of time before we fall away. And falling away leaves us in a precarious position in our relationship with God.
