God’s people have many needs and vulnerabilities but God’s Spirit has been given to help meet those needs and minister to our weaknesses. As rebels against God, we need saving, so the Holy Spirit regenerates, making believers new creatures who are born again from above. We need security in and assurance of that salvation, so the Spirit indwells us, seals us, and testifies to us that we belong to him. We need truth in a world of deception, so the Spirit teaches us. We need fellowship with our Saviour and with his people, so the Spirit unifies us. We need to be holy, so the Spirit sanctifies us. We need guidance and power, so the Spirit fills us, leads us, and prays for us. 

But there is another great need of humanity for which the Spirit was sent to address: the need for all people to be convinced of the serious nature of sin.
