All believers have the Spirit within them; that’s how they are born again.
Not all knowers about Jesus are actual followers of Jesus. They may even go to a church every week but that could be for many reasons such as earning their way into heaven or just habit.
Every tree that does not bear good fruit is cut down and thrown into the fire. Therefore by their fruits you will know them. “Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven. Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’
All believers are in the Spirit, again, because they are born again and alive in Christ. Paul’s message in Romans 6 is that all believers have been set free of the control of the sin nature/power of sin, and therefore, do not have to obey the old man and sin.
Again, only those who are natural followers of Jesus actually are His. Those who have an active sin nature are not.
Again, you cannot be born again without the Spirit. The infilling of the Spirit is a secondary event- this is why Wesleyan thought calls this a second work of grace- that empowers people for service.
The evidence of being born again of the Spirit is a new nature that cannot break the commandments of God. 1 John 3:9. This is the first event, not the second. There is a secondary event for service, but the taking away of sin from our nature is being born again and first.
Whoever has been born of God does not sin, for His seed remains in him; and he cannot sin, because he has been born of God.
Beloved, if our heart does not condemn us, we have confidence toward God. And whatever we ask we receive from Him, because we keep His commandments and do those things that are pleasing in His sight. And this is His commandment: that we should believe on the name of His Son Jesus Christ and love one another, as He gave us commandment. Now he who keeps His commandments abides in Him, and He in him. And by this we know that He abides in us, by the Spirit whom He has given us.
Generally speaking, most do not believe in tongues, but I would not be one of them. It is not necessarily the same for all the gifts of the Spirit.
Though speaking in tongues is real and an outward sign, it can be faked by anyone. If someone really wants to know if they are actually born again they need just ask themselves if they always receive what they pray for.
No doubt! But that would not be very likely in conservative Wesleyan churches. The UMC has left Wesleyan theology far behind in many cases.
Yes, as did mine.
