I do however believe that you have to allow God to work in and through you to fulfill His purpose in your life. This process starts by you believing that God has a purpose and that He can fulfill His plans for your life.
In Luke 1 Mary, the mother of Jesus believed that nothing is impossible for God (verse 37) and she made herself available for God’s purpose (verse 38). Because of that she was called blessed:
And blessed (happy, to be envied) is she who believed that there would be a fulfillment of the things that were spoken to her from the Lord.
You don’t only have to believe that God has a plan, but you also need to believe that there will be a fulfillment of that which was spoken to you from the Lord!
Maybe you don’t know what God has said about you.
In Jer. 29:11 the Word says that the plans He has for you, are good plans. If you realize this God says the following in verse 12 and 13:
Then you will call upon Me, and you will come and pray to Me, and I will hear and heed you.
Then you will seek Me, inquire for, and require Me [as a vital necessity] and find Me when you search for Me with all your heart.
If you accept in faith that His plans are good for, then you can call upon Him and He will hear. You can seek Him and you will find Him! And in Him you will find the purpose of your life!
