The term is "present truth" and was used in Russell's day (if not even earlier). The phrase is also used by many other modern Bible Student and Adventist groups.
Now, let's stretch our legs and join in song:
Song 91
Taught by Jehovah
(Isaiah 54:13)
1. Jehovah sends out light and truth; He is our Grand Instructor. He leads his sheep so patiently As their Divine Conductor. His time has come for all to learn That he is the Supreme One, Who lovingly provides instruction That the meek ones does bestir. His Master Worker, Jesus Christ, Was greatest of earth’s teachers. He spoke the things his Father taught, Explaining Kingdom features. As chicks are gathered by a hen, He seeks in love to help all men. Today he teaches, just as then, The sheeplike ones within his pen.
2. Jehovah gives us shepherds too, Who strive to teach with insight. Their educated tongue reflects That in their heart they’re upright. The weary ones they seek to help. Unruly ones they counsel By teaching what is true and right; In this Jehovah takes delight. Taught by Jehovah now we are; His Son directs the teaching. A priv’lege we indeed do have As truth our hearts is reaching. If fondness in our hearts will burn For those who for the truth do yearn, It’s by proclaiming all we learn, They may to God in worship turn. 3. "Come, learn about Jehovah God," That is our invitation. A teaching work is under way That promises salvation. By printed page and word of mouth, The good news of God’s Kingdom Is being preached throughout the earth To ev’ry tribe and nation. As fellow workers, we have need In faith to be progressing And keep in step with
present truth, His Kingdom to be stressing. And soon through Christ’s Millennial Reign, The resurrected ones will gain Instruction so they may attain To perfect life in earth’s domain.
