If you were baptized by full immersion in water, then you are likely to be in the millennial kingdom of God, unless there are other factors, such as being too late to respond. However, if you were baptized yet still have no golden crown, it may be that you forgot to say "Jesus is Lord." In order to have the crown of righteousness, you must have been forgiven of all your sins. However, you cannot be forgiven unless you acknowledge that Jesus is Lord.
There are many who have been chosen to serve in the millennial kingdom, including some who have been appointed as priests of God, who still have no crown of righteousness. Speak now to the Lord God Almighty, in the language of the spirit, from the heart, and acknowledge to him that "Jesus is Lord." It was his sacrifice, and his alone, that cleanses every sinful thought, word, and deed.
The Lord God Almighty El Shaddai
