Colossians 1:28…”He is the one we proclaim, admonishing and teaching everyone with all wisdom, so that we may present everyone fully mature in Christ.” Wrong theology will never produce spiritual maturity. A right understanding of God’s word is necessary for right living, and in particular the gospel, which is:
God – Is our creator and is perfectly holy and perfectly just. He made us to obey him as His creation.
Man – We have all chosen to disobey him and sin against Him. He punishes sin with eternal torment and separation from him in hell.
Christ – Jesus lived a perfectly obedient life and died on the cross for our sins. On the cross, he took on the punishment we deserve, was raised from the dead and is now seated at God’s right hand interceding on our behalf.
Response – We can be saved from God’s wrath and have Christ’s perfect life counted as ours, bringing us into a right relationship with God if we repent and believe in Him. Those who repent and believe will enjoy God forever in heaven.
False gospels do not bring about maturity in Christ, because they distort what God is really like, minimalize the human condition and/or misunderstand the object of our faith (i.e. health and wealth in this life). In all cases, when Jesus is not highly esteemed, and when He is not the object of our affections, then we will not grow in holiness.
