Believe on the Lord Jesus Christ, and you will be saved.
You can know God, that is have a personal relationship with Him. He is the Creator of all things; He knows all, sees all and has all power, and yet He loves us all and wants us to return that love. As someone has said, God is larger than the universe, but may still live in your heart. Knowing God, receiving eternal life, being saved, becoming a new creation, all are terms expressing what happens when a person believes on the Lord Jesus Christ. If you are not sure about being saved, you owe it to yourself to make sure.
Christ gave His life on the Cross as the payment for all sin, and then He arose from the tomb and ascended to Heaven. He is alive forever and makes intercession for us today.
If you feel led to trust in Christ, that means the Holy Spirit is calling to you. Allow the Spirit to change your heart about anyone or anything you believe will allow you into Heaven, other than Jesus. We are all sinners; we make mistakes, we believe, say and do things we should not. We need a Savior. No good works are good enough to earn Salvation. It takes believing on Jesus Christ to get to Heaven.
Here are some Bible verses to help you:
Jesus said, I am the way, the truth and the life. No one comes to the Father but by me. John 14:6
For all have sinned and come short of the glory of God. Romans 3:23
If you will confess with your mouth the Lord Jesus, and believe in your heart that God has raised Him from the dead, you will be saved. Rom. 10:9
For God loved the world so much that He gave His only begotten Son, that whoever believes in Him shall not perish, but have everlasting life.
You are saved by grace through faith, and that is not of yourself: it is the gift of God. Ephesians 2:8
Will you abandon everything the world has offered to convince you that you will be ok when you die? If it were possible for us humans to earn Heaven, Jesus would not have had to die on Calvary. Believe in the Truth.
Call on the Lord. He is the only way, and He is only a prayer away.
