For though by this time you ought to be teachers, you need someone to teach you again the first principles of the oracles of God, and you have come to need milk and not solid food."

Hebrews 5:12 (NKJV)

Most people join a training club to improve their skills or learn new ones. Even though the church is not one, if it were, it would be the only club I am aware of where members can choose not to grow or maintain a healthy spiritual lifestyle. In order to push and stretch themselves beyond their current capabilities, the same individuals can accept challenges and harder work from their coaches or trainers, but they might not respond in the same way to their church leaders.

The writer of the epistle to the Hebrews had to teach the most basic and simple truths of the gospel again to his readers. Despite having had time to mature in their faith, it appears as if they were infants again, still needing to drink spiritual milk and not ready for spiritual meat.

Any believer who keeps on drinking "milk" remains immature and is inclined to selfish preoccupation,

It will be quite difficult for such immature believers to distinguish between good and evil, truth and deception, and right and wrong. It will also be challenging for them to live righteously and act justly in practical situations. This is because they will behave more pragmatically than Scripturally, doing what suits them and not considering what the Spirit of God is saying through Scripture. They will become unproductive and shallow as a result of preferring to live by the flesh than by the spirit.

Now, if you have been a believer for some time, you ought to move from a "spoon-fed" faith to a “self-feeding” faith. Instead of relying too heavily on others to prop your faith, you must learn to take charge of your own spiritual growth and development.

Cultivate a voracious appetite for God's Word and delve deeply into it. God will give you the ability to understand and put into practice the truths He shows you. Then you will not only possess and enjoy what is rightfully yours in Christ but also impart to others that which you have received (Colossians 2:10).
