I really love how revelation begets more revelation. How you can't understand something till you've understood something else. I love the Holy Spirit! He's such a great teacher. I so enjoy sitting at His feet and learning. I love how He will share with me anytime of the day or night. I could be anywhere doing anything and He will reveal something to me. He has had me dwelling on,  ruminating on, this thought all day -  

"Always bearing about in the body the dying of the Lord Jesus, that the life also of Jesus might be made manifest in our body". 

This scripture helps me to understand so many other scriptures.  It's the key to unlocking the understanding that has eluded me for so long. I touched on one aspect of this earlier when I wrote about our old man and new dwelling in us at the same time but I've always wondered why certain scriptures tell us to mourn this life while others tell us to rejoice and be glad. I used to think it meant there is a time and a season for both in our lives - but there's more to it than that because His dying (His death) and His (ressurection) life are in us simultaneously.  We can both grieve and mourn over the sin in our own heart as well as the sins of (with the deadly results) of the fallen world we live in, while at the same time rejoicing and being exceedingly glad for the beauty and holiness of the next world to come "He that hateth his life IN THIS WORLD (in this flesh) shall keep it unto life eternal"

"I say to you, that you shall weep and lament, but the world shall rejoice: and you shall be sorrowful,  but your sorrow shall be turned into joy." "The ransomed of The Lord shall return, and come to Zion with songs and everlasting joy upon their heads: they shall obtain joy and gladness, and sorrow and sighing shall flee away".

The more i study the topic of Biblical rejoicing,  the more i see -  it's all for the life to come. It's all for the One who brings us to that life and through this one. Concerning this present world - and the life we live in the flesh, we grieve and mourn- we weep and are exceedingly sorrowful, for our own sins and the sins of others. We hate this life, we hate being seperated from God because of sin, and when we are reunited with Him because of His blood, we hate that so many remain seperated from Him. It kills us to know so many beautiful people, such precious souls, made for His pleasure, are going to Hell, are apart from Him now and will remain so forever.  At the same time our heart beats out with great sorrow it beats in with great joy that "we are in this world but not of it". Look at these scriptures pertaining to rejoicing- 

"MANY SHALL REJOICE AT HIS BIRTH" We rejoice for righteousness being born in our flesh, not for the flesh itself. We rejoice  that our names are written in Heaven (Luke 10:20), we rejoice whenever one of God's lost sheep are found (Luke 15:6), we rejoice because we will see Him again (John 16:22). We rejoice because we have access by faith into the grace wherein we stand - and we rejoice in hope of the glory of God. We rejoice that Christ is preached. The focus is on Christ and His finished work on the Cross, and on the glory to come. We do not rejoice for this world, so full of rebellion and sin. Listen to Paul -

"But this i say brethren, the time is short: it remaineth, that both they that have wives be as though they had none; and they that weep, as though they wept not; and they that rejoice, as though they rejoiced not; and they that buy, as though they possessed not; and they that use this world, as not abusing it, for the fashion of this world passes away".

Weep with those who weep, mourn with those who mourn, rejoice with those who rejoice - see? We are instructed to both weep and rejoice, together, in one breast. We are called to do both - hate the old man, love the new. If we pluckbout the eye of the old man we will stop seeing what he wants to see - pornography,  perversion, violence and other sins, but our new man will have other eyes, eyes that continually seek to behold Him, our Christ - the beauty of holiness.  If we cut off the hand of our old man we'll stop doing what he enjoys - we'll stop sinning - while our new man has two good hands with which to do many good works - 

"put you on the Lord Jesus Christ,  and make not provision for the flesh, to fulfill the lusts thereof"
