“I am the bread of life,” Jesus told them. “No one who comes to Me will ever be hungry, and no one who believes in Me will ever be thirsty again. But as I told you, you’ve seen Me, and yet you do not believe. Everyone the Father gives Me will come to Me, and the one who comes to Me I will never cast out. For I have come down from heaven, not to do My will, but the will of Him who sent Me. This is the will of Him who sent Me: that I should lose none of those He has given Me but should raise them up on the last day. John 6:35-39 HCSB
When we give ourselves to Jesus fully, we are saved. Jesus is our Protector, He is our Shepherd, He is our Light; He will not leave us or abandon us as long as we fully come to Him. We are His if we truly believe in Him and follow His commands.
