Spiritual maturity is what happens spiritual growth is accomplished. You can’t have spiritual maturity without spiritual growth. Before you’re mature in something, you must have grown in it.
Spiritual growth is what takes place immediately after salvation. Salvation is a one-time experience; spiritual growth is a continuous process. Salvation is God’s job; spiritual growth is your job. When a sinner receives the gospel, he gets salvation, but when a believer receives the gospel, he gets spiritual growth. The same message, but two different jobs.
2 Peter 3: 18 [KJV] – But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ. To him be glory both now and forever. Amen.
Spiritual growth means to grow in grace (Jesus) and his knowledge. The Greek word translated for knowledge here is Epignosis. Epignosis is a kind of knowledge that comes to you through participation. This kind of knowledge is full and accurate; it is the highest kind of knowledge.
There’s another kind of knowledge that comes by revelation (ginosko) i. e when something is revealed to you; another one by awareness (aido), but this one comes by participation; there is a relationship between the knower and the object known. This knowledge causes spiritual growth.
Therefore you must have full and accurate knowledge of:
(a) The knowledge of the truth (Jesus) – 1 Tim 2: 4
(b.) The knowledge of yourself in the truth (Jesus) – Philemon 6
Spiritual growth is the process of knowing Jesus fully and accurately, following Jesus wholeheartedly and becoming more and more him.
CONFESSION – My faith active and alive. I grow, mature and follow Jesus daily. I make progress in my knowledge of Jesus and Jesus alone. Amen
