Scorchi made some wonderful comments in the last post, so I suggest that you read those comments. I also suggest that you read a conference talk by Henry B. Eyring, called O Remember, Remember. Here's a quote from that talk:
My point is to urge you to find ways to recognize and remember God’s kindness . . .
And the challenge to remember has always been the hardest for those who are blessed abundantly. Those who are faithful to God are protected and prospered. That comes as the result of serving God and keeping His commandments. But with those blessings comes the temptation to forget their source. It is easy to begin to feel the blessings were granted not by a loving God on whom we depend but by our own powers.
Later on, he says:
There is a simple cure for the terrible malady of forgetting God, His blessings, and His messages to us. Jesus Christ promised it to His disciples when He was about to be crucified, resurrected, and then taken away from them to ascend in glory to His Father. They were concerned to know how they would be able to endure when He was no longer with them.
Here is the promise. It was fulfilled for them then. It can be fulfilled for all of us now:
“These things have I spoken unto you, being yet present with you.
“But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.”5
The key to the remembering that brings and maintains testimony is receiving the Holy Ghost as a companion. It is the Holy Ghost who helps us see what God has done for us.
Take time to read Brother Eyring's talk. He urges us to notice and record our many blessings as a way to see the hand of God in our lives. And that will help us remember.
