Even today, many are still blinded from the truth even if the truth is clear because sin blinds us in deep denial. Jesus said he came to testify about the truth, which is ‘Jesus himself’ who came to die on behalf of us as the word, אֱמֶת (truth), in Hebrew clearly described. He came to us to prove, testify His Love for us.
He proved himself who he is by walking on the earth and dying on the cross and being resurrected from the death, He is who He says He is, and He can and will do what he says He can do for us.
May God give you a revelation of knowing him in a special way today. "In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning.Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of all mankind. The light shines in the darkness, and the darkness has not overcome it.” (John 1:1-5)
