The mature Christian exhibits the fruit of the spirit (as described in Galatians 5:22-23) as the consecrated servant is governed by the Holy Spirit at all times. Pure character is refined through sanctification (as in Romans 6).
God gives everyone a gift. While the supernatural gifts of the spirit (as in 1 Corinthians 12) may come and go, the core areas of personal and professional aptitude likely maintain or increase as the Christian grows in grace.
When God saves you, He also often calls you. The exact calling may not be immediately apparent. But for the mature Christian, the calling will be increasingly obvious. It often aligns with character and competence.
When God calls you, He also often supplies you to fulfill your calling. The called servant, operating on the narrow path, will see their steps ordered and needs supplied in the same way as manna was supplied to the Israelites
