Due to the world's rejection of the absolute truth of the Bible, and thus the absolute truth of God's definition of manhood, masculinity has become culturally irrelevant. This is the strategy used by the enemy in his attack on manhood.
When we understand that true manhood comes from God and God alone, it becomes our responsibility to emulate His character, as to fulfill our commission of biblical masculinity.
Boys grow up clueless regarding what it means to be a man, when they don't have an example in a father figure to follow. Manhood is inherited from the example of a godly father, more than it is learned from pastors in a church. Manhood is passed down from father to son.
Boys will learn manhood by witnessing the lifestyle of a father figure who reflects the nature of God, and draws his sense of validation and identity from his relationship with God.
