When you know what your Spiritual gifts are, you are better able to serve the Lord and those around you. You won't be signing up to do something that you will regret later.
Rather, when you serve the Lord with the gifts that He hand picked for you, you will THRIVE! Serving is much easier that way. You will find joy in your heavenly job!
Don't let this verse from Matthew be true because of you! You can be a blessing to the Kingdom! The very Kingdom that you will be spending all of eternity serving God in!
Matthew 9:37-38 (NIV)
Then he said to his disciples, “The harvest is plentiful but the workers are few. Ask the Lord of the harvest, therefore, to send out workers into his harvest field.”
I've often heard people say, "I don't care what my job in the Kingdom will be. Just give me a broom and I will sweep streets, as long as I get there!"
That isn't a Biblical or even Godly perspective of the Kingdom. You have all of the power that raised Christ from the dead at your disposal! Find out what your gifts are and go use it!
