God instills gifts, talents, and passions within each of us. These things often push us towards our purpose. Created uniquely, we as believers all make up the body of Christ. Without eyes, one could not see. Without legs, one could not walk. Remember, we don't have to serve the Kingdom, we get to.
The eye cannot say to the hand, “I don’t need you!” And the head cannot say to the feet, “I don’t need you!” On the contrary, those parts of the body that seem to be weaker are indispensable... (1 Corinthians 12:21-22)
