How do we know we are lacking in spiritual growth?

The concept of feeling lacking in spiritual growth is deeply rooted in the believer's awareness of their ongoing struggle with sin and their desire for sanctification. In Philippians 4:12-13, Paul shares his experience of being both content and aware of his deficiencies. This dual awareness—that we are complete in Christ yet feel a need for growth—is essential for authentic Christian living. The Holy Spirit initiates us into the mystery of our faith, revealing both our completeness in Christ and our need to grow in grace and knowledge (2 Peter 3:18). The presence of this tension leads believers to actively seek God for wisdom and strength in their faith journey.
