A verse so small, but it brings such deep truths.
We have the audacity to think that most of us will go to heaven to live with God. But all our wrong belief falls apart when we came across this verse.
We learn here that eternal life is given us by God through His Son Jesus Christ. So only through Him. There is nothing I can do to make me able to enter heaven. There is nothing anyone can do for me to open up the entrance doors to live with God. The only person who could do this is God, and he has done through his Son Jesus.
Another thing we learned here is that only those who have the Son is to be entitled to eternal life. There is another way, another path, another possibility. If you have the Son have life. If you do not have the Son does not have life. That simple. Perhaps too simple for some people to accept.
