It is loving to not let the neighborhood bully on your property with your kids. Even so Jesus is not being unloving to not let Sinners into Heaven.

How do you know that He will let you in unless He has saved you from your Sins.
Repent and Believe in Jesus to Save you FROM your Sins. Be Baptized to Jesus Christ for the Remission of your Sins and you shall receive the Holy Spirit. And He shall cause you to keep His commandments and judgments and do them.
