Just because something has been told doesn't mean it has been taught. Likewise, it's possible to teach without ever telling anything.
I came to understand this while a full-time missionary. In working to help my fellow missionaries learn to be more effective, frustrations would arise. Missionaries would have trouble understanding why those they teach just don't seem to understand basic teachings, even after being explained to them.
I'd often ask, "Has that really been taught to them, or have you only told it to them?"
Occasionally, I'd illustrate the point by declaring the following:
I can tell you how to play the piano in one sentence. Are you ready to learn? All you do is press the correct key, at the correct time, and hold it down for the correct length of time.
That's it.
Now, go forth! Be thou a concert pianist!
The truth is, I really did explain all that's involved in playing the piano perfectly. But of what value is this explanation at really teaching someone how to play?

We can teach people things without ever explaining them, as well.
As part of their everyday work, missionaries are often told to reschedule their teaching appointments endlessly, as a result of something always coming up in the way. There are real problems if the missionaries always say, "no problem, we'll just reschedule."
What missionaries usually mean by this is, "we want to be courteous and respectful of your time." They may even say those things occasionally.
However, what is being said there is not what is really being taught.
What is being taught is: "Appointments with missionaries are not very important, because any little thing that comes up as an excuse to fail to keep the appointment should always take precedence. Learning the Gospel of Jesus Christ is only something that we fit into our busy lives if we have the time left over, by the rare chance that there are some scraps remaining after all other pursuits have taken what they want out of our valuable time. Jesus shouldn't be the center of our lives, but out on the periphery, only welcomed in when we think we have the time."
Of course, missionaries would never say those things, but they sometimes clearly teach it by their actions.
And likewise, there are many good things taught by action or example, that don't need to be told to be understood.
How powerful can be a righteous example!
However, being "an example of the believers" involves explicit teaching of the word of the Lord. Because we've been commanded to share the Gospel, we cannot fully live it without teaching it to others. (1 Timothy 4: 11-12)
So, tell others of the marvelous gifts you've received by your decision to follow the Savior. Teach them of the love they can enjoy walking with Him. Testify of the truths you share. Invite them to act.
It takes a lot of practice over time. Like beautiful music waiting to ring out, these things cannot be forced. It must be coaxed out by diligent practice and training.
Far beyond the notes printed on the page, you will find your own style of beautiful sounds to contribute to God's work, within the framework He has established.
See all there is to learn, and begin learning it. Every bit of effort you invest will pay back dividends beyond your full ability to predict.
Tell, teach, testify, invite. Encourage, uplift, sustain.
You are doing better than you think. Keep going.
