Sealed and Prepaid

Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavens, in Christ; for He chose us in Him, before the foundation of the world, to be holy and blameless in His sight. In love He predestined us to be adopted through Jesus Christ for Himself, according to His favor and will, to the praise of His glorious grace that He favored us with in the Beloved.

In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace that He lavished on us with all wisdom and understanding. He made known to us the mystery of His will, according to His good pleasure that He planned in Him for the administration of the days of fulfillment—to bring everything together in the Messiah, both things in heaven and things on earth in Him.

In Him we were also made His inheritance, predestined according to the purpose of the One who works out everything in agreement with the decision of His will, so that we who had already put our hope in the Messiah might bring praise to His glory.

In Him you also, when you heard the word of truth, the gospel of your salvation—in Him when you believed—were sealed with the promised Holy Spirit. He is the down payment of our inheritance, for the redemption of the possession, to the praise of His glory.
(Ephesians 1:3-14 HCSB ©®)

You are quite likely to be and do all that He has ordained to become so. I expect the only way you could fail would be by quitting. He chose you, He has given you a seal, and He has put part of your inheritance in the Kingdom in you ahead of time to connect you to success that will drag you forward into completion. You are awesome. Live it.
