There is a definite why to know what your calling is. Many people go through years and years of their life without know what their purpose and calling is. This is tragic because it isn’t that difficult to discover.
Your calling is where your deepest heart desire is met and you are truly satisfied and free. If your heart desire keeps coming back to you, and this desire is not contrary to the word of God, then it’s most likely from God.
“Rejoice always. Pray without ceasing. In everything give thanks, for this is the will of God in Christ Jesus toward you. Don’t quench the Spirit. Don’t despise prophesies. Test all things, and hold firmly that which is good. Abstain from every form of evil.” (1 Thessalonians 5:16-22)
