"You took one phrase from Eph 1:11, spun it to suit your particular supertition,"

No, the paragraph is quite clear that one who trusts in Christ (not works for salvation and not trust and works for salvation) is sealed by the Holy Spirit, which is our escrow, security deposit, until the day of redemption. It can't be more clearer unless you have ears that refuse to hear or eyes that refuse to see. Believers are sealed and nothing can break that seal or separate us from the love of God which is in Christ Jesus. Neither you nor I are gods able to defeat the seal of God. Satan will try to break it with the 144,000 and Revelation 14:3 says he will fail.

Do you really think we are stronger or wiser than Satan?

The sealing of the Holy Spirit can be onto condemnation of one who apostacizes (Luther comes to mind). But it has nothing to do with once-saved-always-saved superstition or else Paul would have stopped at Ephesians 1:11 and did not write the exhortations to works of charity in 2-6.
