We need religion to know about God and to receive salvation. It is like saying whether we need to go to hospital to receive medical care. We really need to have religion before we can be saved. Religion is the doorway that opens unto God and leads us unto God. We cannot roll away religion when we are talking about the things that pertain to the salvation of our soul. Religion is good. It is not a bad thing if we receive salvation. Many people do not agree to the terms of salvation. A lot of people think that salvation is not a needful thing when talking about God. But how could we have known about God if there wasn't anyway he would have been revealed unto us?
Salvation can only come from God. And we needed to understand this God. God's ways are not clear to us except we learn about them. So, we were taught about God through religion. So religion became the agency that exposed us to God. We must be reconnected back to God. Because we were disconnected from God due to our sins. The Bible says that our sins had separated us from God. We must be led back to God and to receive salvation from Him. Religion is the channel through which people are reconnected back to God. Therefore, we really need religion in our life.
