Some enter the Christian life through the narrow gate while others appear to enter by climbing over the wall. Both people seem to be on the journey to heaven. A Christian who came in over the wall never left their sin and never fully surrendered their life to Jesus. They still wanted to be somebody.
Many people never truly repent and surrender–which means to leave all sin and give yourself completely to Jesus Christ. Without this foundation–you will not cannot build an honest Christian life that is acceptable to God.
If you arrived at the Judgment Day today, would God say, “You entered by the narrow gate?” Or would he say, “You climbed over the wall?”
