I forgot how challenging assembling a puzzle can be until working on one with my wife and daughter. The puzzle required a lot of work – figuring out which pieces fit together, and which ones did not. The same is true of our lives. Through our trials and circumstances, God has given us all the pieces (patience, love, strength, intellect, faith, forgiveness, etc.) we need to live a purpose driven life:
We have different gifts, according to the grace given to each of us. If your gift is prophesying, then prophesy in accordance with your faith; if it is serving, then serve; if it is teaching, then teach; if it is to encourage, then give encouragement; if it is giving, then give generously; if it is to lead, do it diligently; if it is to show mercy, do it cheerfully (Romans 12:6-8).
Therefore, it becomes our responsibility to work towards putting those pieces together. Pursue your God given passion no matter how you may feel or what your present circumstances may be. Write the book, go back to school, start the business, etc. Do not give up on yourself. If God has given it to you, then He will use those gifts that are within you for His glory.
Commit yourself to working towards putting the pieces God has bestowed upon you together and watch Him do immeasurably more than all you can ask or imagine, according to his power that is at work within you (Ephesians 3:20).
