What is your next step on your walk with Jesus?
This is a very personal question. It is based on where your life is at present. It needs to factor in where you have been and where you hope to go.
Ultimately, it is about taking a single step. Have you made a public profession of faith and been baptized? Then, do those. Have you served the Lord in any capacity? Then, find a place to serve. Have you read a single book in the Bible? If not, start with the Gospel of Mark or Luke. Have you ever prayed about anything? Start with a simple one-minute prayer time.
Be honest about your current position in your walk of faith. Then take a step. There are a thousand possible things you can do, but do something.
