Definition: Recognition of the quality, worth, or significance of people and things.

1. In the Bible, the Lord often expressed His appreciation by giving people credit, praising them for their good qualities, or for making the right decisions.

Job 1:8 And the Lord said unto Satan, Hast thou considered My servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil?
Acts 13:22b And [the Lord] said, I have found David the son of Jesse, a man after Mine Own heart, which shall fulfil all My will.
John 1:47 Jesus saw Nathanael coming to Him, and saith of him, Behold an Israelite indeed, in whom is no guile [deceit]!
Luke 7:9 [Referring to the faith of the centurion whose servant Jesus healed:] When Jesus heard these things, He marvelled at him, and turned Him about, and said unto the people that followed Him, I say unto you, I have not found so great faith, no, not in Israel.
Luke 16:8a [Jesus even praised the unjust steward for his wisdom:] And the Lord commended the unjust steward, because he had done wisely.
Matthew 15:22-28 [Jesus praised the Canaanite woman who did not get offended at His hard saying:] And, behold, a woman of Canaan came out of the same coasts, and cried unto Him, saying, Have mercy on me, O Lord, Thou Son of David; my daughter is grievously vexed with a devil. 23 But He answered her not a word. And His disciples came and besought Him, saying, Send her away; for she crieth after us. 24 But He answered and said, I am not sent but unto the lost sheep of the house of Israel. 25 Then came she and worshipped Him, saying, Lord, help me. 26 But He answered and said, It is not meet to take the children’s bread, and to cast it to dogs. 27 And she said, truth, Lord: yet the dogs eat of the crumbs which fall from their masters’ table. 28 Then Jesus answered and said unto her, O woman, great is thy faith: be it unto thee even as thou wilt. And her daughter was made whole from that very hour.

2. The Lord  also commends us when we invest our talents wisely to help others and further His Kingdom.

Matthew 25:21 [In the Parable of the Talents, Jesus narrated:] His lord said unto him, Well done, thou good and faithful servant: thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord.
Luke 12:37 [Jesus said:] Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them.
Hebrews 6:10 For God is not unrighteous to forget your work and labour of love, which ye have shewed toward His Name, in that ye have ministered to the saints, and do minister.

3. The Lord wants us  also to show appreciation to others.

So the Kenites departed from among the Amalekites.
1 Samuel 25:32-33 And David said to Abigail, Blessed be the Lord God of Israel, which sent thee this day to meet me: 33 And blessed be thy advice, and blessed be thou, which hast kept me this day from coming to shed blood, and from avenging myself with mine own hand.
