Yes, there is one more coming of Christ, TO THE EARTH. Jesus’ 1st advent as well as His 2nd advent are to Israel. And yes, for the benefit of all peoples of all nations also. The pre-tribulation rapture is Christ’s catching away of His bride and hardened Israel will go through the last 7 years decreed for them in Daniel 9:24(the 144,000 Israelites are God’s servants, or remnant at that time). This is not “sickening” or a “false gospel”.
