This account is found in 3 of the 4 Gospel records: Mark 1:1-11, Matthew 3:1-17 and Luke 3:1-22. As we read about John The Baptist calling people to repentance we see one of the pre-requisites of baptism for a follower of Jesus. We also see this clearly in Acts 2 as Peter tells the people to repent and be baptized for the remission of sins. Clearly, the Christian life is centered upon our repentance from sin and our turning to The Way of Jesus. This is not only something that happens before baptism but this is a daily calling for us.
We cannot 'go our own way' and 'follow Jesus'. Those two things are in direct opposition to one another. The life of a Jesus Follower is a life that is lived counter-culturally...against our own human nature and against the norms and standards of life around us.
True, if you have turned towards Jesus and never turn back then you have done well. However, most of us find that life is full of opportunities to 'turn back to Jesus' again after we have made choices to try it on our own. Inspect your own life and see where fresh repentance is needed.
A great prayer for us as we inspect our life is found in the Psalms:
Search me, O God, and know my heart; test me and know my anxious thoughts. Point out anything in me that offends you, and lead me along the path of everlasting life. (Psalms 139:23-24 NLT)
Asking God to search you and point out areas of needed repentance is a humbling and powerful act.
