But I have always struggled with feelings that I do not measure up.
Of course, that is they way they hook people in, the feeling is totally common to JWs.
Or having a portion of the Holy Spirit, like others speak of.
The WT don't want you to believe this but the text speaks loud and clear
Acts 2:17-18 (New International Version)
17 " 'In the last days, God says,
I will pour out my Spirit on all people.
Your sons and daughters will prophesy,
your young men will see visions,
your old men will dream dreams.
18 Even on my servants, both men and women,
I will pour out my Spirit in those days,
and they will prophesy.
And once again, later in the same chapter "all" is used, not just a select few
Acts 2:38-39 (New International Version)
38 Peter replied, "Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit. 39 The promise is for you and your children and for all who are far off—for all whom the Lord our God will call."
And again, the Holy Spirit is for us all who believe and He is our guarantee
Ephesians 1:13-14 (New International Version)
13 And you also were included in Christ when you heard the word of truth, the gospel of your salvation. Having believed, you were marked in him with a seal, the promised Holy Spirit, 14 who is a deposit guaranteeing our inheritance until the redemption of those who are God's possession—to the praise of his glory.
Blessings,
Stephen
