This isn't on God. He never instructed us to divide into doctrinal groups. Now everyone wants to be like CT Russel and start their own religion.
Let me just correct you there......C.T. Russell did not “start” our religion.....being a gifted public speaker and with very good Bible knowledge, he was a spokesman for a group who met together regularly to examine the accepted doctrines and compare them with the scriptures, to see if they were true and if they were not from the Bible to find out where the teaching originated.
These men were from different denominations of Christendom and had only one goal...to discover the truth no matter how painful that might prove to be.
In careful examination of the scriptures, as a group in unanimous agreement, they arrived at that truth and promoted it. That led to the formation of the International Bible Students Association, which attracted like-minded souls who were also fed up with corruption in the church and wanted “the truth...the whole truth...and nothing but the truth”. In fulfillment of Bible prophesy, from small beginnings, a mighty nation would grow. Just like ancient Israel, spiritual Israel (“the Israel of God”) would also spring from small beginnings. (Galatians 6:16)
Jesus warned however, that “weeds” would be sown in Christianity and that both the “wheat and the weeds” would “grow together until the harvest time". There have always been true and false Christians in the world, but the genuine Christians have always been in the unpopular, even hated minority. (John 15:18-21)
Our Father is always directing us, always speaking to us, but we've essentially been taught that God doesn't speak anymore and that He is unapproachable, so we don't listen and we struggle to understand Him. We live in a fallen world. We design doctrinal statements that become our platform of identity.
That does not alter the fact that in these “last days” Jesus was to appoint a
“faithful and wise slave” who was to “feed” his fellow slaves their
“food at the proper time”. (Matthew 24:45)
According to the apostle Paul, there are only two tables at which to feed....
“...I am saying that these sacrifices are offered to demons, not to God. And I don’t want you to participate with demons. You cannot drink from the cup of the Lord and from the cup of demons, too. You cannot eat at the Lord’s Table and at the table of demons, too.” (1 Corinthians 10:20-21 - NLT)
If we are not feeding at the table of the Lord, then we are feeding at the table laden with poisonous demonic lies. Can we tell the difference? The Bible indicates that the master deceiver would fool the majority into feeding at the wrong table.
We see that at the time of the judgment, Jesus rejects those who thought they had it all right....when they offer him their excuses, he tells them that he “NEVER” knew them.....how did they not know? (Matthew 7:21-23) “NEVER” means “not ever”.
How many did Jesus say were on the cramped road to life? Not the “many” but the “few”. (Matthew 7:13-14)
Jesus knows those who belong to him, and who are teaching the truth....his Father will invite those ones into his family of worshippers. No one can come to the Son unless the Father invites them. (John 6:65) We will all know soon enough who they are.
God doesn't see or care so much about doctrine as we so, He wants us to love Him and love each other. In THAT, we are in agreement.
He wants us to love the truth....that goes along with loving God and his Christ. Teaching false doctrines is what God hates, as Jesus demonstrated when he said to the Pharisees.....
“You hypocrites! Well did Isaiah prophesy of you, when he said: 8 “‘This people honors me with their lips, but their heart is far from me; 9 in vain do they worship me, teaching as doctrines the commandments of men.’” (Matthew 15:7-9 - ESV)
So God does care about what we believe and teach....
With regard to love, Jesus said....
“If you love only those who love you, what reward is there for that? Even corrupt tax collectors do that much. If you are kind only to your friends, how are you different from anyone else? Even pagans do that. But you are to be perfect, even as your Father in heaven is perfect.” (Matthew 5:46-48 - NLT)
Nothing is “perfect” if it isn’t true......what you accept as truth...matters.
