There are so many things people tend to believe. The horror of it all is that people believe in the majority; things that are said without taking the time to do the research themselves.
Having confidence in anything that you don’t know the full truth of is harmful to you. Having faith in anything other than GOD is false worship of another god. Having trust in someone or something can cause you pain. You have given someone or something an unrealistic expectation. When that expectation is not met, negative emotions arise.
There is only one person who you can have full confidence in. There is only one person who you can have full faith in. There is only one person to trust. GOD the Creator; JESUS the Word and SON of GOD; Holy Spirit the Comforter to all Born Again CHRISTians.
When you question whether simple believing is enough think about this.
I tell you the truth; anyone who believes has eternal life. John 6:47
Believe in The LORD, JESUS and you will be saved. Acts 16:31
