PHILIPPIANS 2:13-15 ~ “for it is God who works in you both to will and to do for His good pleasure. Do all things without complaining and disputing, that you may become blameless and harmless, children of God without fault in the midst of a crooked and perverse generation, among whom you shine as lights in the world,”
In the movie, “Meet My Mom”, the ten-year old Jared was feeling melancholic that he and his mom had to move to California to live with his grandma—hoping to make a better life after his dad and mom got divorced. As his mother tucked him in for bed, Jared was busy whining about: not liking the color of his room ... missing his friends and school back home ... his dad's ignoring him ... asking his mom why her and his dad are separated ...” Thankfully, the wise mom was able to shed good thoughts into Jared’s young mind by stating reasons to be thankful. To paraphrase, she said to him, “Jared, there are lots of reasons to be thankful for—you may not like the color of your room but at least we have a place to come to … your grandma provided us a roof over our head … I got a new job … being in a new community gives us an opportunity to meet new friends and learn something new … what happened to your dad and I, was something beyond my control …” “No matter what we have to be thankful for what we have.” “We have each other”, she added.
Our circumstances may not be all that sweet, but wherever we are it's God's will that we give thanks in everything in Christ Jesus (1 Thessalonians 5:18). As a Christian, that is possible because no matter what our circumstances are, we can always thank God for deliverance through Christ. He conquered our sins by His death on the cross, rose from the dead, and lives (Hebrews 12:2; Mark 9:9; 2 Timothy 2:7-9; Romans 7:24-25; Romans 8:11; 2 Corinthians 2:14; Hebrews 7:24-26).
Not a single Scripture in the Bible talks of the Lord Jesus complaining, He did the opposite instead. Knowing who He is, gives Him the right to complain the most but then He did not. Therefore, who are we to whine.
Certainly, the Israelites knew that thanksgiving was of utmost significant—that part of the official duty of the tribe of Levi was to thank God: “They are also to stand every morning to give thanks and praise to the Lord, and likewise in the evening.” (1 Chronicles 23:30). They had heart of thankfulness and were commanded to be thankful regardless of what transpired that day.
So, the psalmist inscribed: “Enter into His gates with thanksgiving, And into His courts with praise. Be thankful to Him, and bless His name.” (Psalm 100:4). Discern that we are instructed to enter God’s gates with a heart of thankfulness and praise His name. We cannot enter into His gates in the absence of thankfulness, with whining, grumbling, or murmuring. That’s how important it is to worship the Lord with a thankful heart. Not that we give thanks to the Lord only for those favorable situations but also for those which are not. Being thankful not for men's applause or for the inheritance that awaits for those who serve God but to the greater glory of our Lord and Master, Jesus Christ.
"And whatever you do, do it heartily, as to the Lord and not to men, knowing that from the Lord you will receive the reward of the inheritance; for you serve the Lord Christ." (Colossians 3:23-24)
“Give thanks in everything, for this is God’s will for you in Christ Jesus.” (1 Thessalonians 5:18) … “And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him.” (Colossians 3:17) … “giving thanks always for all things to God the Father in the name of our Lord Jesus Christ,” (Ephesians 5:20).
