Whenever you get a sense of what God is really calling you to, you may have a lot of questions. How is this ever going to happen? How can I ever get to the place I want to be? Is this really possible?
If God put it in your heart, then yes, it is possible. He will equip you to do what you need to do. His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him who called us by glory and virtue. (2Pet 1:30) You’d be surprised by how much He put in you already. Start working what you know.
And then, pay attention to the people He puts around you. Do you keep running into someone with knowledge that would be helpful to you? Stop and consider what you can learn from other people. Why reinvent the wheel if you can learn it from someone else, at least the parts that you need to learn. It’s wisdom to learn from others. Take advantage of the knowledge base that’s out there, and use it in the area that you are working.
Your destiny will take time to work out. Don’t expect it to land in your lap. Be patient. Do the things that you know to do and take steps to get to the next place. God will open doors for you as long as you are working toward the goal He gave you.
