This verse makes it very clear that Jesus is the only Way to obtain salvation. Being good will not get you in, keeping the 10 Commandments will not get you in because no one can keep all 10, all the time. Not only is Jesus the only way, He is also the Truth, there is no falsehood in Him. Finally, He is the Life, His death, burial, and resurrection sealed the deal on making us New Creatures in Him. In addition, He has given us the Holy Spirit so that He can live His life through us.
