It takes more than just believing in God, even Satan believes in God.
If you haven't done so lately, take a minute and praise God for your salvation through your faith in His Son. It only takes a minute to affirm your trust in Him, but the rewards are eternal.
Those along the path are the ones who hear, and then the devil comes and takes away the word from their hearts, so that they may not believe and be saved.
Luke 8:12 (NABRE)
