God’s expectation for His children is that we might be righteous, holy and true to His Word and will. While we know this cannot be accomplished while we remain mere infants in Christ, spiritual maturity is something that for many Christians is either illusive or beyond their grasp to attain. Part of problem lies in our “worldly” thoughts, words and deeds portray that while the power of sin to rule over us has been crucified with Christ, we have chosen to allow our “old nature” to continue to be our master. But even if one could clearly see and confess the “planks” in one’s eyes this still leaves one with an even bigger problem: how does one define and strive to become spiritually mature in Christ Jesus? If one is able to become a living sacrifice, think with the mind of Christ, reject the ways of this world and obey His word while at the same time carrying the burdens of others; does this mean one has attained spiritual maturity? Even if this list were comprehensive whom amongst us could ever attain God’s overarching standard of holiness? The following sermon is going to examine Philippians 3:15 and in doing show that spiritual maturity is possible for those who deny self and relentlessly pursue He who is the definer and source of all holiness!
