1 John 2:29 - 3:6 / John 1:29-34
It is said that a book is not judged by its cover.
That is quite true because until the contents are read, then the book can be judged accordingly.
But in terms of unity of appearance and substance, then the cover of the book should be worthy of the contents of the book.
Similarly, in our unity of life, our appearance and our character should have a co-relation.
In the gospel, John the Baptist was able to recognize Jesus as the Lamb of God.
John the Baptist had received a revelation that the one on whom the Holy Spirit come down and rest upon is the Chosen One of God.
And it also could be possible that John the Baptist had already noticed that there was something unique about Jesus.
It could be in His appearance, or how He spoke, or what He did.
We are disciples of Jesus, and we follow Jesus as our Master.
Disciples should be like their Master, and hence we should be like Jesus.
May others see Jesus in us, and just as Jesus offered His life for the salvation of the world, may we also offer our lives in service of others.
