Maturity is not a given with numerical age. Wisdom is not necessarily something that comes with the passage of years. To grow beyond yourself is surely a start.
See the needs of others. Be a blessing.
Instead of chasing after things, seek the Lord’s wisdom for your life. Let Him work in you and through you for the glory of His Kingdom “for such a time as this!”
For it is written:
“If any of you lacks wisdom, let him ask of God, Who gives to all liberally and without reproach, and it will be given to him.”
