How long is eternity?

Just imagine how long it would take if a bird can pick up every grain of sand and dirt from the earth one at a time and deliver it to the moon. This length of time is unknown, and it would take a very long time. With this in mind, it is just a drop of eternity.
Satan, who is the god of the sinful world, has blinded people in their minds that they are unable to see the light of Christ and to discern eternity. If Satan can blind people in their minds, then people will see what they want to see and become deceived. Satan has convinced many people he does not exist, and he has reasoned with people’s motives that have distracted people from God by trying to make the most of this life with fun, entertainment, and living a life of freedom. This life style is the way that seem right to a person, but in the end it leads to eternity in a place called hell.  
"Satan, who is the god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ, who is the image of God." 2 Cor 4:4
"There is a way that seems right to a man,
But its end is the way of death." Prov 14:12
