Salvation through Jesus Christ is the only way to gain access to Heaven once you enter into Eternity. These are some simple steps to gain Salvation.
1. Recognize that you are a sinner
Romans 3:23 states that "all have sinned and come short of the glory of God".
2. Repent of your sins
Repenting of your sins means to show true remorse for the bad things you have done in life. Luke 13:3 states that "..but unless you repent, you will all perish as well.."
3. Accept that Jesus Christ is the only method of true salvation from our sins
John 14:6 - "Jesus saith unto him, 'I am the way, the truth, and the life; no man cometh unto the Father, but by me'"
4. Rejoice in your newly-found relationship with the Lord.
Romans 10:13 - "For whosoever shall call upon the name of the Lord shall be saved."
