It is not any individual sin that has the power to keep from heaven, but the one of refusing to be saved.
It is horrible enough as it is on earth, but think about this: We are watching a picture of eternal death when we watch the slaughter of abortion. Think of what it symbolizes in terms of souls never seeing the light of Christ. Permitting yourself to be born again is needed to see eternal life. Abortion stops people being born. The things that are needless stumbling blocks in God’s kingdom stop people from being born again.
Not my point.
