In the bible, we learn that there is only one way to heaven. Only one way to an eternal life with God, the Creator and Sustainer of everything. That is, by trusting in Jesus, the Son of God (John 3:16). Christ came to earth (Philippians. 2:6-11) to make a way for humans to be reconciled with the Father.
God is holy, perfect and just. According to the Apostle Paul, all have sinned and all fall short of God’s standard (Romans 5:22-24). However, Paul also states that ALL have access to grace. Yes, forgiveness of sins (justification) is available to those who truly know and trust Jesus as Lord and Saviour.
This is because Jesus is holy, perfect and just. The unblemished Lamb of God.
