We have come to share in Christ, if indeed we hold our original conviction firmly to the very end

Hebrew 3:7-19
See to it, brothers and sisters, that none of you has a sinful, unbelieving heart that turns away from the living God. But encourage one another daily, as long as it is called “Today,” so that none of you may be hardened by sin’s deceitfulness. We have come to share in Christ, if indeed we hold our original conviction firmly to the very end.
Today, if you hear his voice, do not harden your hearts as you did in the rebellion.
And to whom did God swear that they would never enter his rest if not to those who disobeyed? So we see that they were not able to enter, because of their unbelief.
This whole passage is rooted in the Greek version of Psalm. Those to whom this letter is addressed are in a very similar position to Israel at the time of the exodus. Both have seen God at work in an amazing way. But despite this, the Israelites rebelled against God in the desert. 'They did not believe' - and so a whole generation forfeited their right to enter the promised land and enjoy the rest God would have given them. Be warned. What happened then can happen now., if those who hear God's message do not accept it. 
Why?
There are history shows to us Israelite unfaithful to the Lord so they could not enter the promised land. So it is the truth now if we hear the voice of the Holy Spirit, but harden our heart will be forsaken by the Lord.
All Christians have come to share in Christ, if indeed we hold out original conviction firmly to the very end may enter the rest of the Lord

提出反面的警告： 不得進入安息。
不可硬著心，只是觀看，神的作為即神的道路。在危難時，只是看神的作為，看看這個時候神可以變出什麼把戲來。40年以色列人觀看神的作為，帶著輕蔑的眼光。遇到困難就抱怨摩西，從未沒有為此感恩！沒有從神蹟因而更去依靠神。他們只要神蹟，不要神的人，他們常常心裏迷糊，不明白神的道路。神要以色列人不要憂慮吃什麼穿什麼，神必供應。這是外邦人求的。
不得進入安息，因為人不想在神的家享受安息，而去外面，自己找的。
有警告也有勸勉
v12-13 完全的依靠，就要完全順服，樣樣都有。從神的供應中看見神的心意！

Be faithful to Jesus Christ and be encouraged among Christians.
