“For so an entrance will be supplied to you abundantly into the everlasting kingdom of our Lord and Savior Jesus Christ.”
will be supplied to you
The word “supplied” means to furnish or provide (at one’s own expense, cf. 1:5). “Supplied” in the Greek originally meant to supply the finances for the chorus of the Greek drama. This person was exceeding wealthy for the costs of the drama were very extensive. God will provide whatever is necessary to meet our needs.
Our access into heaven will be in an abundant manner. In the passive (as here), it means that God will grant us an entrance into heaven.
The word “abundantly” means in large amounts with the implication of being valuable (Ep 2:4).
Jn 10: 10 “The thief does not come except to steal, and to kill, and to destroy. I have come that they may have life, and that they may have it more abundantly.”
The Christian will have a grand entrance into heaven (1 Th 1:9; 2:1; He 10:19). God grants us access into His presence. Every Christian has eternal life but not every Christian has an abundant Christian life.
God spares no expense in meeting our needs.
We supply the virtue and God supplies our abundant entrance into heaven.
As there are two ways to live the Christian life, so there are two ways to enter the everlasting kingdom. We enter the kingdom when we receive Jesus as our Savior. We enter the kingdom abundantly when we live a victorious Christian life. That is a bonus. Not all Christians will have the same status in the eternal kingdom.
