So how do we know that SDA is true? Based on your explanation, you are suggesting that SDA is the only ones delivering truth, and in your case, truth that saves. I will be honest, any time anyone tells me that they are the only ones who got it right, I run! That includes Calvinists too btw.
Please read one more time what was stated. Then:
1 Timothy 3:15 KJB - But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth.
Where is this house, which is the church of the living God, being the pillar and ground of truth?
There are a thousand broken glass shards, but one diamond. It is not boastful to simply relate what scripture teaches.
Revelation 12:17 KJB - And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
Where are these people that the dragon is specifically "wroth" with, who are the "remnant", that "keep the commandments of God" [that's the Ten Commandments], and have the "testimony of Jesus Christ", which is the "spirit of Prophecy" [Revelation 19:10 KJB]
Where is this group that prophesies from the
portion of the [previously sealed; Daniel 12:9, now open, Revelation 10:2 KJB] book of Daniel that was sealed until the time, having experienced a bitter experience, but were to prophesy again after it?:
Revelation 10:2 KJB - And he had in his hand a little book open: and he set his right foot upon the sea, and his left foot on the earth,
Revelation 10:10 KJB - And I took the little book out of the angel's hand, and ate it up; and it was in my mouth sweet as honey: and as soon as I had eaten it, my belly was bitter.
Revelation 10:11 KJB - And he said unto me, Thou must prophesy again before many peoples, and nations, and tongues, and kings.
What
one "body" of people have the gift of prophecy manifested in it:
Ephesians 4:11 KJB - And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;
Ephesians 4:12 KJB - For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
Ephesians 4:13 KJB - Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:
Ephesians 4:14 KJB - That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;
Ephesians 4:15 KJB - But speaking the truth in love, may grow up into him in all things, which is the head, even Christ:
Ephesians 4:16 KJB - From whom the whole body fitly joined together and compacted by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in love.
What single "body" is warning the whole world, and is of all nations, proclaiming the 4th Commandment, to return to the worship of the True Creator God, the LORD of the Holy 7th day the Sabbath:
Revelation 14:6 KJB - And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people
Revelation 14:7 KJB - Saying with a loud voice, Fear God, and give glory to him; for the hour of his judgment is come: and worship him that made heaven, and earth, and the sea, and the fountains of waters.
What "body" is preaching against the Great Whore of Romanism, and warning of her Daughters of Revelation 17 KJB?
What "body" of people are seen in existence after the 1,260, 1,290, 1,335 and 2,300 of Daniel?
What "body" shows the way of salvation/redemption through the sanctuary:
Psalms 77:13 KJB - Thy way, O God, is in the sanctuary: who is so great a God as our God?
John 14:6 KJB - Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
Who teaches that Jesus Christ after His crucifixion, death, burial and resurrection and ascension
began His High Priestly Ministry at Pentecost, to officiate the true Sacrifice which He gave of Himself, having to fulfill the remaining Feasts, from Pentecost to Tabernacles?
Hebrews 8:1 KJB - Now of the things which we have spoken this is the sum: We have such an high priest, who is set on the right hand of the throne of the Majesty in the heavens;
Hebrews 8:2 KJB - A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man.
Hebrews 8:5 KJB - Who serve unto the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount.
Where is the "body" that obeys the command of Christ to wash one another's feet at the Lord's supper?
John 13:14 KJB - If I then, your Lord and Master, have washed your feet; ye also ought to wash one another's feet.
John 13:15 KJB - For I have given you an example, that ye should do as I have done to you.
John 13:16 KJB - Verily, verily, I say unto you, The servant is not greater than his lord; neither he that is sent greater than he that sent him.
John 13:17 KJB - If ye know these things, happy are ye if ye do them.
Look for the identifying marks, and many more could be given, and you will find the "one fold". After that there is no where to run to, except into the dens of the earth that the rocks may fall upon them, for they will have been running since Genesis.
