Alistair Begg explains that as believers grounded in God's mercy, we are called to offer ourselves as living sacrifices, resist conformity to the spirit of the age, and pursue inward transformation through the Holy Spirit's renewing work. The Christian life, he reminds us, is a journey of lasting obedience, built on the trust that God's purpose is to make His people increasingly like Christ.
