There is Safety in Thanksgiving
Having a thankful heart keeps us in a "safe place" - a place where Satan cannot gain access to our minds. That place is where we give thanksgiving and praise to God for ALL He has done for us. "In everything give thanks; for this is God's will for you in Christ Jesus" (1 Thessalonians 5:18).
I have a friend who is a pastor and he recently went through a situation in his church where many people in his congregation left. Instead of becoming embittered about what he had lost, he made a conscious effort to thank God for the people who stayed with him. In a time of loss, it is easy to lose sight of all we still have! In all circumstances and at all times, we must find something to be grateful for, and remain thankful in the place God has put us.
During times of crisis and fear, we also have a choice to make - will we continue to trust God? When fear is running rampant, will we follow the norm or become a beacon of hope? Will we continue to put God first? Will we put our faith in fear or God? Christians have nothing to fear. If we die, we go to heaven. And in any other trouble, God will sustain us. God's power can and will show up anywhere we give it access to by thanking HIM instead of giving way to fear.
"Be anxious for nothing, but in everything by prayer and supplication WITH THANKSGIVING let your requests be made known to God. And the peace of God, which surpasses all comprehension, will guard your hearts and your minds in Christ Jesus" (Philippians 4:6-7 emphasis mine).
The presence, peace and power of God are gifts given freely to those who trust Him and do not allow fear and anxiety to remain in their heart. The peace of God will guard our heart, fighting against anxiety and dissatisfaction. Anxiety will erode our faith and trust in God, but the peace of God that passes all understanding will produce a thankful heart. I truly believe that a thankful heart will touch God and enable us to experience His presence anywhere at anytime.
