Martin Sim is a devout Christian with a heartfelt desire to help others know the truth of Christ and the importance of His Word.

In an inspirational guide, Sim explores the art of missional giving by returning to one of Christ's most powerful commandments--the Great Commission. While encouraging believers and church leaders that when we reengage with the dynamic "Book of Acts" model and bring the first 15 percent of our efforts and resources toward the war effort of the Commission, that these actions will allow the church to once again find its joy, purpose, peace, and calling. By utilizing the simple first 15 model, Sim reminds believers that it is well in their ability to change a world to see a kingdom and what they will receive if they follow Christ's mission and restore themselves to the needs of the poor and needy, the lost, and those without hope. All when we go outside of ourselves.

The Second Part of the Equation shares stories and scripture that show a clear path and demonstrate viable reasons for the church, its leaders, and its followers to return to its original mission.
