The caveat in my statements is whether God has laid Sabbath on someone's heart, and their response to that calling. Our relationship with God is about progressive revelation, where He is always teaching us, and always causing us to see things in our life, and in His Kingdom, that we have never seen or known before.
Think about the things you know and do today in your relationship with Him, that you didn't do last year. Did you love God last year? Were you trying to live your life in an honoring way? I would hope so. But just because you didn't know everything and didn't do everything doesn't mean you were disobeying God and not loving Him. Similarly, how many things are you going to know and do next year that you're not doing now? Do we still love God today and are trying to live our lives in an honoring way? Again, I would hope so.
The reason I said that "Both of us will be in the Kingdom of God" is because Jesus said it.
Matthew 5:19
"Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven."
Both the obedient and the disobedient will be there, but the ones who DO obey will be considered greater because showed their love by walking out obedience.
We walk on a slippery slope when we imply that someone has to obey all of the commandments or else they don't love God. That's where we get to the point of requiring everyone to do everything in the Law in order to be saved. Because it means that if you are not wearing tassels on the ends of your garments (Num 15:38), they you are willingly and and knowingly disobeying God's commandments.
Are you wearing your tassels right now, Frank? Because according to your standard, if you're not wearing them you don't love God.
It is amazing how many people will defend the work of Satan because they are not interested in defending the Word of God. So many people find so many excuses possible to defend their own stance because it is convenient for them as all their friends and families are doing the same and if everybody is doing that, surely that should be OK hey, as everybody cannot be wrong? Newsflash, God is a God of Love but He hates those goes against Him. Please do yourself a favor and go and read Hebrews 3 and 4 and discover some Truth. The path to the Kingdom of God is narrow and those who do not strive to be on this Narrow path, will NOT be in the Kingdom of God one day. I do my best to please God in every possible step I take and I know that God will forgive me where I have failed. I also know that the more I do what He wants me to do, the more light I will receive from Him. I know that I will be judged on what I know. I do NOT challenge God in any way because I feel that I have a right to do so. I also believe there is a ranking order in heaven as those who will be standing in the Truth at the end of times, will be placed on thrones where others won't. But I doubt it if there will be one Sunday Keeper who knew about the Sabbath and ignored it. You try to convince me that everybody will be in the Kingdom of God but believe me when I tell you that there will be many that will be destroyed by fire and brimstone that will never ever enjoy the Kingdom of God. You have still a lot of study to do before you can make statements like what you have done. I will pray that God will open your eyes to His Word and to receive the wisdom to understand so that you may be saved one day.
