18 Bible Verses about Spiritual Maturity

But [we are different, because] our citizenship is in heaven.

Therefore let us get past the elementary stage in the teachings about the Christ, advancing on to maturity and perfection and spiritual completeness, [doing this] without laying again a foundation of repentance from dead works and of faith toward God, of teaching about washings (ritual purifications), the laying on of hands, the resurrection of the dead, and eternal judgment. [These are all important matters in which you should have been proficient long ago.] And we will do this [that is, proceed to maturity], if God permits.

But the fruit of the Spirit [the result of His presence within us] is love [unselfish concern for others], joy, [inner] peace, patience [not the ability to wait, but how we act while waiting], kindness, goodness, faithfulness, gentleness, self-control. Against such things there is no law.

For this reason, since the day we heard about it, we have not stopped praying for you, asking [specifically] that you may be filled with the knowledge of His will in all spiritual wisdom [with insight into His purposes], and in understanding [of spiritual things], so that you will walk in a manner worthy of the Lord [displaying admirable character, moral courage, and personal integrity], to [fully] please Him in all things, bearing fruit in every good work and steadily growing in the knowledge of God [with deeper faith, clearer insight and fervent love for His precepts];

until we all reach oneness in the faith and in the knowledge of the Son of God, [growing spiritually] to become a mature believer, reaching to the measure of the fullness of Christ [manifesting His spiritual completeness and exercising our spiritual gifts in unity]. So that we are no longer children [spiritually immature], tossed back and forth [like ships on a stormy sea] and carried about by every wind of [shifting] doctrine, by the cunning and trickery of [unscrupulous] men, by the deceitful scheming of people ready to do anything [for personal profit]. But speaking the truth in love [in all things—both our speech and our lives expressing His truth], let us grow up in all things into Him [following His example] who is the Head—Christ.

But you did not learn Christ in this way! If in fact you have [really] heard Him and have been taught by Him, just as truth is in Jesus [revealed in His life and personified in Him], that, regarding your previous way of life, you put off your old self [completely discard your former nature], which is being corrupted through deceitful desires, read more.
and be continually renewed in the spirit of your mind [having a fresh, untarnished mental and spiritual attitude], and put on the new self [the regenerated and renewed nature], created in God’s image, [godlike] in the righteousness and holiness of the truth [living in a way that expresses to God your gratitude for your salvation].

Therefore as you have received Christ Jesus the Lord, walk in [union with] Him [reflecting His character in the things you do and say—living lives that lead others away from sin], having been deeply rooted [in Him] and now being continually built up in Him and [becoming increasingly more] established in your faith, just as you were taught, and overflowing in it with gratitude.

For though by this time you ought to be teachers [because of the time you have had to learn these truths], you actually need someone to teach you again the elementary principles of God’s word [from the beginning], and you have come to be continually in need of milk, not solid food. For everyone who lives on milk is [doctrinally inexperienced and] unskilled in the word of righteousness, since he is a spiritual infant. But solid food is for the [spiritually] mature, whose senses are trained by practice to distinguish between what is morally good and what is evil.

Therefore let us get past the elementary stage in the teachings about the Christ, advancing on to maturity and perfection and spiritual completeness, [doing this] without laying again a foundation of repentance from dead works and of faith toward God, of teaching about washings (ritual purifications), the laying on of hands, the resurrection of the dead, and eternal judgment. [These are all important matters in which you should have been proficient long ago.]

So put aside every trace of malice and all deceit and hypocrisy and envy and all slander and hateful speech; like newborn babies [you should] long for the pure milk of the word, so that by it you may be nurtured and grow in respect to salvation [its ultimate fulfillment], if in fact you have [already] tasted the goodness and gracious kindness of the Lord.

Therefore, [let me warn you] beloved, knowing these things beforehand, be on your guard so that you are not carried away by the error of unprincipled men [who distort doctrine] and fall from your own steadfastness [of mind, knowledge, truth, and faith], but grow [spiritually mature] in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be glory (honor, majesty, splendor), both now and to the day of eternity. Amen.
