...till we all attain unto the unity of the faith, and of the knowledge of
the Son of God, unto a full-grown man,
unto the measure of the stature of the fullness of Christ.
You can talk about “growing up” to a child and it sparks a deep interest and desire to be a “grown-up” immediately. Mention “growing up” to a 75-year-old man, and he will think you have trouble understanding the process of aging. If “growing up” is part of a conversation among Christians, it is understood we have a lot to learn.
Not all Christians are “complete unto every work” (2 Timothy 3:17). There are some things lacking about our character we must add before we could be considered “a full-grown man.” Are there not some noticeable signs today of your maturity? Have you been a Christian long enough to have developed some traits that distinguish you from the world? Take a look at some indicators of whether or not you have matured.
Maturity is an ability to base a judgment on the big picture - the long haul.
Maturity is the ability to stick with a project or situation until it is finished.
Maturity is using discretion on what you hear or see that may influence you the rest of your life.
Maturity is making a decision and standing by it.
Maturity is adding self-control to your energies and abilities.
Maturity is living up to your responsibilities by keeping your word and doing your job.
Maturity is the ability to face unpleasant, frustrating, and uncomfortable situations without complaints, excuse, or blame.
Maturity is taking a failure and turning it into a success.
Maturity is keeping your faith “alive” while everyone else is just “keeping” theirs.
Maturity understands you will never know all there is to know, but it does not keep you from learning as much as you can.
