Matthew 18:3 And he said: "Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven.
What does it mean to be become like little children? Apt to learn as they do. A sincere heart and wanting the truth.
Mat 8:12 But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth.
Why were the children of the Kingdom cast out? Because these children did not grow up in all things and come to perfection.
They did not bother to search the scriptures daily to see if the things Paul said were so.
Act_17:11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.
Joh 5:39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
People these days go and listen to a pastor instead of searching the scriptures ourselves. We believe that asking JESUS to come into our heart is the salvation plan when it does not say this in the Bible at all. Who came up with this asking JESUS to come into our heart slang? Billy Sunday who played for the White Socks had everyone bow their heads and said the sinners prayer.
Its not even in the Bible but still we take a man's word for it over the Word of God. Paul the Apostle was baptized in JESUS Name. Peter and all the rest in the scriptures did the same as well as the church but we today have rejected the oracles of God and went with our pastors that hardly read the Bible all the way through even one time.
