We are not allowed into Heaven by how good we are. We are allowed into Heaven by accepting the gift of God's only Son who died for our sins past, present and future. We need to just believe and accept this gift. This  in no way gives us freedom to sin. 1 Peter says be holy for I am holy. But if we fall it in no way removes us from our spot given us in heaven. We must ask forgiveness and get up and move on from sin as God will give us a clean slate daily if we ask Him.

Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others; For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself. And as it is appointed unto men once to die, but after this the judgment: So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
Hebrews 9:25‭-‬28 

Be Blessed,
