The way we walk in faith is through our conduct, lifestyle, and choices. The Holy Spirit guides our steps, and we purposefully follow. It is important that we ask for direction and wisdom, except that He will answer and meet our needs, and trust that He knows what is best.
Becoming a Christian doesn't mean that obedience to the Lord is automatic. It's a lifelong process of growing in our trust and patiently waiting on Him before we act. This requires a steadfast commitment to obey so that we can say no to ungodly choices and yes to God.
