If you want your life to be fulfilling, then give it purpose.
A father builds his life to provide for his family.
An athlete builds his life to support his team.
A soldier builds his life to protect his nation.
A Christian builds his life to honor God.
What impact will your life have? Will you affect your own family? Your community? Your nation? Your sense of fulfillment will largely depend on how much impact you perceive your life having.
Of all the things you can focus on, honoring and focusing on God have the biggest impact. They impact your family, your team, your community, your nation, and the entire world.
Your impact will be unmeasurable and eternal.
If you want your life to matter, give it an infinite impact...
