(1 John 2:6 KJV) He that saith he abideth in him ought himself also so to walk, even as he walked.
The evidence of the reality of salvation is in the life that we live. If we claim that we live in Him, and He lives in us, then that reality will be shown in the way we live. We will live our life like He lived His life, endeavoring to have His attitudes, to talk and act as He would. If we claim to live in Him, our life should give evidence of His presence with us.
