Jesus began his public preaching career around the age of 30 and lasted for about 3 years: * * Baptism and Temptation * *: He was baptized by John the Baptist in the Jordan River, and the Holy Spirit descended like a dove (Mark 1:9-11); Then he fasted in the wilderness for 40 days and defeated the devil's temptation (Matthew 4:1-11). -Calling disciples: Select 12 disciples (such as Peter, John, etc.) and walk with them to preach. - @dcbvxsdg19
