Pretty simply, actually. His pre-existence (yesterday) is explained as a special case:
Unlike any other human, Jesus lived in heaven as a spirit person before he was born on earth. (John 8:23) He was God’s first creation, and he helped in the creation of all other things. He is the only one created directly by Jehovah and is therefore appropriately called God’s “only-begotten” Son.
Jesus' resurrection returned him to his spirit-being (today and forever):
After Jesus died, God restored him to life as a spirit person. (1 Peter 3:18) Jesus then waited at God’s right hand until Jehovah gave him power to rule as King over all the earth. (Hebrews 10:12, 13) Now Jesus is ruling as King in heaven, and his followers are announcing that good news worldwide
