Never doubt God. The Bible says very clearly, God cannot lie. Therefore, one who is wise, a true believer is going to want to base his or her life upon the word of God. So again, never doubt God. I do not know why so many people do not believe what God has said, for example, and First John chapter five and verse 13. John writes down these words, he says, I've written to you, that you will believe in the name of the Son of God, believing in the name, knowing his identity, who Messiah is, and what he has done, gone to that cross, that He has been raised from the dead victoriously so that you might believe in the name of the Son of God, and through believing that you will know here that, that you will know that you have eternal life.
