I tell you the truth, wherever this gospel is preached throughout the world, what she has done will also be told, in memory of her." (Matthew 26:13)
While Jesus was in Bethany in the home of a man known as Simon the Leper, a woman came to him with an alabaster jar of very expensive perfume, which she poured on his head as he was reclining at the table. When the disciples saw this, they were indignant. "Why this waste?" they asked. "This perfume could have been sold at a high price and the money given to the poor." Aware of this, Jesus said to them, "Why are you bothering this woman? She has done a beautiful thing to me. The poor you will always have with you, but you will not always have me. When she poured this perfume on my body, she did it to prepare me for burial. (Matthew 26:6-12)
Whatever we do for the Lord Jesus and his kingdom with love in our hearts is like beautiful fragrance in his presence. Here, the woman brought very expensive perfume which she poured on his head. What we offer for the expansion of God's kingdom here on earth may not be as costly as what the woman brought, but it has great value in the eyes of the Lord.
And Jesus' promise that "wherever this gospel is preached throughout the world, what she has done will also be told, in memory of her." has been proved true. It has been read & it has been preached about countless times.
So do not consider the work that you are doing for the Lord to be trivial. Do it with all your heart. You will be rewarded in the Lord's good time.
The Bible says,
Therefore, my dear brothers, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain. (1 Corinthians 15:58)
God bless you.
