Mike Bickle emphasizes Jesus' invitation for everyone to pursue greatness in His kingdom, highlighting that this desire is part of our spiritual DNA. He explains that true greatness is not about worldly recognition but about obedience to God's commandments and living according to the Sermon on the Mount. Bickle encourages believers to actively seek this greatness, which will be fully realized in the age to come, rather than in the present. He warns against the passive attitudes that neglect this divine invitation and stresses the importance of teaching and influencing others in their spiritual journeys. Ultimately, he calls for a radical commitment to living out God's commands as a pathway to true greatness in His sight.
