I will try to answer both your questions. First we are told in John 17:3,"And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent." Eternal life can be thought of as something that Christians experience now. Believers don’t have to “wait” for eternal life, because it’s not something that starts when they die. Rather, eternal life begins the moment a person exercises faith in Christ. It is our current possession. John 3:36 says, “Whoever believes in the Son has eternal life.” Note that the believer “has” (present tense) this. The focus of eternal life is not on our future, but on our current standing in Christ.
