The seal of the spirit!
'The Father has set his seal' on Christ (John 6:27) and also seals us in him (cf. 2 Corinthians 1:22; Ephesians 1:23, 4:30). Because this seal indicates the indelible effect of the anointing with the Holy Spirit in the sacrament of Baptism,
Baptism indeed is the seal of eternal life." The faithful Christian who I has "kept the seal" until the end, remaining faithful to the demands of his Baptism, will be able to depart this life "marked with the sign of faith," with his baptismal faith, in expectation of the blessed vision of God - the consummation of faith - and in the hope of resurrection.
St. Paul tells the faithful at Ephesus that they have been “sealed with the promised Holy Spirit.” This is in terms of an indelible character imprinted on the soul in the sacraments of baptism and confirmation. It is not as if this invisible mark is simply decorative. Rather, through it, we are enabled to participate in Christ’s mission and in his offices of priest, prophet, and king. Eph 1:13 and cannot be repeated
Sealed by God eph 1:13 sealed by God (ez 36:25-27) in the ark of salvation by baptism just as Noah was sealed by God in the ark of the flood gen 7:16
1 Pet 3:20 Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water.
21 The like figure whereunto even baptism doth also now save us!
(Ark of Noah a type of the church, member of Christ and his church and salvation by baptism!)
(Outside the ark of Noah none were saved, outside the church (the ark of salvation) none are saved!)
Sealed in the ark, sealed in the church the ark of salvation by God thru baptism!
