In general terms, salvation is being rescued (or saved) from a difficult or desperate situation.
The purpose of Jesus’ coming to earth was to die in place of all of us for the wrongs we have done. In essence, he paid our fine and did our time, so that we won’t have to. If we accept this gift or act of Jesus’, it makes us right with God the Father, who is perfect, thereby allowing us to be with him for all eternity.
It’s easy to accept this gift (it’s free) and start on a journey with Jesus. Jesus simply said, “Come, follow me,” (Mark 1:17).
