I am writing today from the beautiful Tampa Bay area.
At the last super, when Jesus tells His disciples that one of them is going to betray Him, they all asked, “Lord is it I? Matthew 26 However, John, instead asks, “Lord who is it?” John 13 John knew it was not Him. He knew that He loved Jesus and had not betrayed Him. John was a confident disciple because he was confident in the love Jesus had for Him and that He had for Jesus. Look at John’s frequent use of the word “know.”
He grasps Jesus’ words, John 17:3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
John himself writes, 1 John 2:3 And hereby we do know that we know him, if we keep his commandments.
2:4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
So John tells us that knowing Jesus equals eternal life, and knowing Jesus equals commandment keeping. If A=C and A=B than C must =B.
1John 2:29 If ye know that he is righteous, ye know that every one that doeth righteousness is born of him.
1John 3:2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
1John 4:16 And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him.
4:17 Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.
John knew the power of a relationship with Jesus, giving him confidence in the judgment, knowing in this world we can experience Jesus’ power over sin.
1John 5:13 These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
John wants us to have the same confidence that he had. He does not want us wondering, or hoping and wishing that we have eternal life. He wants us to know we have eternal life. If we know Jesus, we know we have eternal life. No Jesus, no life.
