You are limiting the gift to Scripture when there is also personal prophecies like the prophecy Agabus gave to Paul, AND what modern prophets do that Peter did on the Day of Pentecost - announce the fulfillment of Joel's ancient prophecy. There is the whole Book of Revelation that has yet to be fulfilled and announced. All the gifts of the Spirit are part of our New Covenant. Some denominations act like they live in a different covenant altogether - one with weaker promises. You need to leave that heretical denomination and give Jesus the credit He deserves and experience the power of the baptism of the Holy Spirit, something most denominationalists have never experienced, and probably never will...even though Jesus said we MUST be born again. What gets born again is our nature. A sin nature to one that partakes of the divine nature of God and is not a slave to sin, but children of God. 1 John 1:9 says we are cleansed of ALL UNRIGHTEOUSNESS. You don't believe that making you an unbeliever in what Jesus did on the cross. I bet you believe the heresy that Jesus just paid our punishment, so we can sin, repent, sin, repent etc. in a never ending life of sin with no punishment or even power to not sin in the first place! No longer committing sin is the reason only our past sins were taken away.
4 by which have been given to us exceedingly great and precious promises, that through these you may be partakers of the divine nature, having escaped the corruption that is in the world through lust.
5 But also for this very reason, giving all diligence, add to your faith virtue, to virtue knowledge, 6 to knowledge self-control, to self-control perseverance, to perseverance godliness, 7 to godliness brotherly kindness, and to brotherly kindness love. 8 ;For if these things are yours and abound, you will be neither barren nor unfruitful in the knowledge of our Lord Jesus Christ. 9 For he who lacks these things is shortsighted, even to blindness, and has forgotten that he was cleansed from his old sins.
10 Therefore, brethren, be even more diligent to make your call and election sure, for if you do these things you will never stumble; 11 for so an entrance will be supplied to you abundantly into the everlasting kingdom of our Lord and Savior Jesus Christ.
