Therefore, rid yourselves of all malice and all deceit, hypocrisy, envy, and slander of every kind. Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation, now that you have tasted that the Lord is good.1 Peter 2:1-3
Getting a taste of the goodness of the Lord causes us to crave more spiritual food. This process of going between hunger and satisfaction is something we physically experience through out the day. We eat and then we get hungry for more. This same dynamic happens spiritually.
And we must continue to feed our souls the spiritual food that it needs because salvation is only the beginning. We are called to “grow up” in our salvation. Maturity was never meant to be an optional part of the Christian life. Salvation is not the finish line but the starting line in our development into a person who looks and acts more like Jesus.
This discipleship, this development and growth in our spiritual life, is vitally important because we were born into a war. We are living in enemy territory and we’ve been commissioned to take ground for the Kingdom of God. Peter goes on to say:
Dear friends, I urge you, as foreigners and exiles, to abstain from sinful desires, which wage war against your soul.1 Peter 2:11
Growing up in our salvation not only means we grow closer to Jesus, but it also means we become more equipped for the battles we face. We get better and better at recognizing the vulnerabilities in our own heart and our own tendencies toward temptation. We get better at recognizing the schemes of the enemy and how he tries to exploit our weaknesses. We train in warfare, learning not only how to defend ourselves but also how to advance and take back ground for the Kingdom of God.
If we never pursue maturity in Christ, we leave ourselves vulnerable, like a newborn baby who never grows up. Instead, we must “throw off everything that hinders and the sin that so easily entangles. And let us run with perseverance the race marked out for us…”(Hebrews 12:1).
