We sure can. It might take a little time, a little investigating, but sooner or later we can know if we are being taught the truth or not. I’m referring mainly to some of the things we have been taught in the churches all these years.
Since childhood, we have been taught that we should celebrate Good Friday because Christ was crucified on Friday. Is that what God’s word says? No it doesn’t say that at all. If we believe what it says, then we know that it took place on Wednesday. If we believe man instead of God, most likely we will be deceived sooner or later. John 19:14 says it was the preparation day, Wednesday, the day of the crucifixion. John 19:31 says the body couldn’t remain on the cross during the Sabbath for that day was a high Sabbath; that was Thursday so he was put in the tomb before the beginning of the high Sabbath; at sundown on Wednesday, the Sabbath began. This would be the first Sabbath of that week; there is another Sabbath coming. Mark 16:1, when the Sabbath was past, Mary had bought the spices and ointment to anoint the body of Jesus (that was the first Sabbath). Luke 23:56 they returned and prepared the spices and rested on the Sabbath according to the commandment. (This is the second Sabbath). So you can see that there were two Sabbaths, or these scriptures would not be true. So we can believe God’s word or believe man; we must decide if we want to please God or be a man-pleaser and believe man.
Have you ever wondered if Good Friday teaching is false? What about Easter? It is also just man’s tradition. The word Easter is not found in the MS and only one time in your Bible. The NIV Bible has translated it correctly, the correct word is Passover instead of Easter. When they seized Peter and put him in prison, Herod intended to bring him before the people after the Passover, not Easter. They wouldn’t have known when Easter was, but they knew when Passover was celebrated, for this happened at the time of the feast of unleavened bread — the time that the passover is celebrated. Have you ever wondered why the word Easter appears only one time when Passover probably 50 or 60 times? Have you read in you Bible where anyone ever celebrated Easter? I don’t believe you have. It found its way into the church, and it came from paganism.
I know most people will not give up these days. We have been taught them from childhood, and it is a decision every person has to make for themselves. Personally, I don’t know why anyone would want to once they heard they are just man’s traditions and not from the word of God.
