The apostle wrote the following scripture for a reason, 2 Timothy 2: 15: Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth. Each one of us are responsible to seek if God truly abides in us. For this is eternal life. (John 17: 1) These words spake Jesus, and lifted up his eyes to heaven, and said, "Father, the hour is come; glorify thy Son, that thy Son also may glorify thee: 2 As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him. 3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent. This what you should seek."
