“For to me to live is Christ, and to die is gain.” Philippians 1:21 Can we say as Paul did, “to live is Christ“? We can only do it if we know the presence of the Holy Spirit within. When we have experienced His presence and leading. For me. speaking and especially singing in tongues confirms the presence of the Holy Spirit within my spirit. The more we experience His presence the less likely we are to quench His work in our lives and grieve Him. “And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.” Ephesians 4:30

What about suffering for Jesus Christ, even rejoicing in our suffering for Him? Once again we can only do this “because God’s love has been poured into our hearts through the Holy Spirit who has been given to us.“
“Not only that, but we rejoice in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope, and hope does not put us to shame, because God’s love has been poured into our hearts through the Holy Spirit who has been given to us.” Romans 5:3-5
“For it has been granted to you that for the sake of Christ you should not only believe in Him but also suffer for his sake, engaged in the same conflict that you saw I had and now hear that I still have.” Philippians 1:29
We will need to know the presence of the Holy Spirit and trust Him implicitly in the soon coming prophesied “end times” because Jesus warns us that there will be great tribulation, such as has not been from the beginning of the world.
“For then there will be great tribulation, such as has not been from the beginning of the world until now, no, and never will be. And if those days had not been cut short, no human being would be saved. But for the sake of the elect, those days will be cut short. Then if anyone says to you, ‘Look, here is the Christ!’ or ‘There he is!’ do not believe it. For false Christs and false prophets will arise and perform great signs and wonders, so as to lead astray, if possible, even the elect. See, I have told you beforehand.” Matthew 24:21-25
