In Ephesians 2:10, Paul tells us that God has prepared good works for each of us to do. Following His plan and doing those good works glorifies Him (John 15:8). It also demonstrates that we are indeed His disciples.
If you experience dissatisfaction as a leader, assess the talents, time, and treasures God has given you. How are you using them? Make adjustments to be on the plan He has for you, using the gifts He gave you.
