To know the TRUTH is to know Jesus Christ, the Living God, not to just know about Him but to know Him for REAL. To walk in truth is to follow and obey Jesus Christ.
Jesus Christ is the WAY, the LIFE and the TRUTH and He gives His Spirit, the Holy Spirit, the Spirit of TRUTH to dwell in those who are born again of the Spirit of God, to those who accept Jesus Christ and submit to Him, to obey Him and to follow Him and to have eternal life. He gives His Spirit, the Holy Spirit in them to guide them into all truth.
This whole world is in the power of darkness through lies and deception and you can only be free from deception and know the truth if you listen to the Holy Spirit and if you follow the guidance of the Holy Spirit. If you do not trust Him, listen to Him and follow Him you will be in darkness, you will perish.
Seek Jesus Christ with all your heart. Seek His indwelling Holy Spirit. He will guide you into all truth. Without Jesus we can do nothing. Without Jesus Christ we are LOST.
Do you know the TRUTH and are you walking in TRUTH? Are you following Jesus Christ?
May Jesus bless you.
