The first birth is physical – by blood, the will of the flesh and the will of man. That’s the story of all of us.
The second birth is spiritual by grace; an unmerited favour.
The third birth is also spiritual, by the transforming power of the Holy Spirit. It’s attained by being full of, living in, and walking with the Holy Spirit till the end.
A born again Christian can miss church rapture for failure to meet the set standard.
A raptured saint can miss inclusion in the Bride and wife of Christ for lack of adequate preparation.
Hence, every heaven-bound believer is expected to work out his or her own salvation with fear and trembling.
As a born again Christian, it is your responsibility to cleanse yourself from every form of filthiness in order to attain the level of holiness required to qualify to participate not only in the rapture of the called-out ones but also to be selected as a bride of Christ.
