What an amazing question!
For me it took 29 years to answer! I’ve been a Christian for 34 years. I’ll answer 3 to 1
#3 ask God to show you your strengths, abilities, and weaknesses.
For Example: While I am a passionate speaker my ability is in teaching, so I find one on one evangelism works for me as opposed to large groups.
#2. Study. Truth Scripture backing this up is Mark 12:30 In my own life I had been loving God with my heart, my soul, and my strength, but I had neglected my mind. 5 years ago I was heavily convicted when I was asked a question about my faith and could not give an answer for the hope that I have.
#1. Allow the Holy Spirit to guide you.
While I can imagine #1 seems like a well duh, my own personal experience is as humans we can be sidetracked by well intentioned Christians trying to help us and we listen to them instead of the Holy Spirits guidance. 1st John 4:1-6 teaches we are to test the spirits to discern if it is the spirit of truth or deceit. When I was younger I tended to listen to others in the church about what I was to do instead of praying and talking to God about their suggestions and if it was Gods will for me.
