“Whoever eats the loaf or drinks the cup of the Lord unworthily will be guilty respecting the body and the blood of the Lord. […] But if we would discern what we ourselves are, we would not be judged.”
~1 Corinthians 11:27,31

The night of Friday, April 19, 2019 corresponds to the start of Nisan 14 on the Jewish calendar.
Jehovah’s Witnesses and friends will be gathering at meeting places around the world to commemorate what Jehovah and Jesus did for us on that day.
The night before his death, Jesus took unleavened bread and a cup of wine to establish a covenant between himself and those he was buying from the earth to become co-rulers with him in Heaven. (Matt. 26:26-29; Rev. 14:3-5)
God’s purpose for humankind has always been that we live forever in a paradise earth. (Gen. 1:28; Ps. 37:29)
But he has lovingly provided an arrangement wherein humans will be judged by peers who have proven faithful to righteous standards. (Rev. 20:6)
Jesus officially founded that arrangement when he shared his last evening meal with his faithful apostles.
How does a Christian know if they are entitled to share in the bread and wine emblems?
God’s spirit manifests itself to loyal individuals who know they are called to rule with Christ in heaven. (Rom. 8:15,16; 1 Thess. 2:12; 1 Pet. 1:3,4)
An anointed Christian experiences great inner change which leads him or her to be certain of his or her own future rather than to wonder about it. (John 3:5-8)
Because most of us are unfamiliar with how it feels to be born in the spirit, we do not judge our brothers who partake in the bread and wine.
