There is far more to your inner life than the food you put in your stomach, more to your outer appearance than the clothes you hang on your body (Luke 12:23 MSG).
Life has much deeper fulfilments than money, material things, and earthly pleasures. Some people have amassed so much wealth and abundant material possessions, yet they aren't fulfilled. Some think that by acquiring more money and properties, making more friends, having more children or getting more famous, they'll finally become fulfilled, but they've realized it's not so. True fulfilment is in discovering your divine purpose; God's will for you in Christ, and accomplishing it.
Jesus said, "…My meat is to do the will of him that sent me, and to finish his work" (John 4:34). That should be your goal, your joy, your fulfilment and satisfaction. You need to realise that man is a spirit being; therefore, the most important things in his life are spiritual. His fulfilment will come from his spirit as he fulfils God's purpose. There's a divine purpose for your life, which you must discover and achieve, for you to be truly fulfilled in life.
Have you asked yourself, "What does God really want for my life?" When you discover His dream for you, be glad about it, and go for it, and you'll be fulfilled. Not everybody may be excited about what God has called them to do, but if you're spiritually minded, you'll be. Be determined to please Him in all things, and He'll fill your heart with joy.
As you study the Word, fellowship with the Holy Spirit and function in the church, you'll discover your specific purpose in Him, and how exactly He wants you to live. That way, life would be more meaningful to you and you'd be able to help others discover their purpose in life, and experience true fulfilment.
Dear Father, thank you for my true fulfilment, which lies in doing your will. You're at work in me, to will and to do your good pleasure. Thank you for guiding me by your Spirit in the direction of your perfect will. My promotion, prosperity, victories, and joy are guaranteed as I fulfil my purpose in you, in Jesus' Name. Amen.
