How can believers walk after the Spirit?

Walking after the Spirit involves a life of faith that trusts in Christ’s saving grace rather than relying on human effort or adherence to the law. Romans 8:4 contrasts walking after the flesh with walking after the Spirit, indicating that true spiritual life is characterized by dependence on the Holy Spirit. This means believers acknowledge their inability to save themselves and instead live in response to the grace of God, allowing the Spirit to guide and transform them into the image of Christ. It is a radical shift away from self-reliance to trust in God’s provision for righteousness.
