I find that many people entertain mistaken ideas about what spiritual maturity involves. They are not growing as rapidly as they could, or they are caught on a level far below where they should be, because they misunderstand what spiritual maturity is and how one grows in grace. The first thing we need to understand is that spiritual growth has nothing to do with our position in Christ. God sees us in His Son as already perfect (Colossians 2:10), and we have everything we need pertaining to life and godliness according to 2 Peter 1:3. Growth is a process by which that which is true of us positionally becomes more and more a reality in practice as well. Every child is born with all the physical traits that they will get. But in order to achieve their potential, they must develop the physical abilities that they have. It is the choices that these new lives make that help determine their growth and development. Growth is what we aspire to not what we have achieved. Just because a baby has all the systems and physical traits they will have as an adult, they must develop those abilities. As you live your life, make choices based on your position, and it is those choices that will not only bring glory to God, but allow you to grow in wisdom and strength.
