Let me say this. You can not “earn” your wings. John 3:16-18 teaches that salvation is a gift to anyone who simply believes (accepts as true) that Jesus is the Son of God. Nothing else what so ever is required. Rest easy my friend. There is no judgement, no tithing , no church. Just believe. Like Paul.
Not only that, but earning “your wings” makes it sound like you will be an angel when you die. God created a finite number of angels. When a saved believer dies, they don’t become angels.
