We have sinned and rightfully deserve Hell. JESUS OFFERS THE FREE GIFT OF SALVATION TO EVERYONE WHO BELIEVES, BY SHEDDING HIS BLOOD. Why is it so hard to accept such a precious Gift freely?
Heaven and Hell are real places and there is no other way to Heaven, except JESUS, FOR HE IS THE ONLY ONE WHO PAID THE PENALTY OF SINS.
How to be sure of being saved or going to Heaven after death?
1) Believe in the One True God(Father, Spirit, Son) and that Christ came down to earth as a man, died on the cross and bought our pardon, and is risen on the third day. Accept Christ ALONE(not self-righteousness, not Mary, not Saints, not religion, not sacraments) as your personal savior.
2) You have received a new heart and new desires. A truly Born-Again believer is a new creation and will have the natural desire to love God and hate sin. They will be extremely sorry when they sin.
It is highly unlikely for a truly Born Again believer to continue with a sinful lifestyle willingly.But, no Christian will be perfect on this side of Heaven.
We are saved by GRACE, through FAITH, in CHRIST ALONE.
Jesus is the ONLY Way to Heaven
