I am writing to you, dear children, because your sins have been forgiven on account of his name. I am writing to you, fathers, because you know him who is from the beginning. I am writing to you, young men, because you have overcome the evil one. I write to you, dear children, because you know the Father. I write to you, fathers, because you know him who is from the beginning. I write to you, young men, because you are strong, and the word of God lives in you, and you have overcome the evil one. (1 John 2:12-14)
Spiritual infancy is mentioned in v. 13. There are different words used in vv.12-13. V. 12 uses a word that is a general word for all believers (ôåêíßá) teknia. V. 13 uses a different word (ðáéäßá) paidia that means a person that is just born and is in the infancy stage as a babe in the Lord Jesus Christ.
So all believers have this in common: our sins are forgiven!
Babies have needs. They need to be fed regularly and often. They need to be dressed, changed, and bathed. They can really do nothing for themselves. It all has to be done for them.
How can you tell if you are still a spiritual infant? Infants have certain characteristics. They are selfish, life is all about them. If they cry they expect you to come running. They make messes.
We need to grow by being in a church that can help care for us. We grow by feeding on God’s Word. We grow by communicating with God in prayer.
