I assure you, most solemnly I tell you, he who believes in Me [who adheres to, trusts in, relies on, and has faith in Me] has (now possesses) eternal life. John 6:47
You do not have to wait on Jesus’ return to become one with Him. Salvations means that you are one with Him right now. You are as saved now as you will ever be. You do not have to become more of a child of God, you are a child of God. You have been born again from God’s Incorruptible Seed. You are His chosen vessel.
For He says, In the time of favor (of an assured welcome) I have listened to and heeded your call, and I have helped you on the day of deliverance (the day of salvation). Behold, now is truly the time for a gracious welcome and acceptance [of you from God]; behold, now is the day of salvation! 2 Corinthians 6:2
Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever. 1 Peter 1:23 KJV
You possess eternal life right now and that means that your Father is able to use you on this earth every bit as much as He will be able to use you in eternity.
Now to Him Who, by (in consequence of) the [action of His] power that is at work within us, is able to [carry out His purpose and] do superabundantly, far over and above all that we [dare] ask or think [infinitely beyond our highest prayers, desires, thoughts, hopes, or dreams]— Ephesians 3:20
