I think this is a thought that many of us go through like a roller coaster ride at times. Then we are left with our poor choses and bad decisions if we do give in to those feelings and frustrations, but does it have to be this way?
God has given us everything we need in order to survive these up and down hills. We just need to access them! So, how do we do that?
The Bible says to "Speak to ourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord;" Ephesians 5:19. This is what He wants us to do in times of discouragement: Access Him through singing and through scripture.
Memorizing scripture is key in the fight of our emotions that can overtake us. We can fight with God's Word and be encouraged through songs that reflect His Glory and Strength. If it were not so, He would not tell us to do it. He knows what will work better than we do. For in our weaknesses, He is Strong.
Take it on your self to incorporate studying God's word together with your children.
~Find scriptures that are geared towards right attitudes toward eachother, towards God, and towards authority.
~Find Hymns and songs that reflect a pure heart, one that emanates God's. One that looks to Him with every word you sing and be encouraged! Let Him purify your heart to have a new focus on the tasks a head of you, that often is too much to bear.
Most importantly of all, make sure you have a time each morning to begin your day in His arms, reading His word and bearing your heart before Him. Pray before the day begins for His strength to guide and help you. I will pray for all of you too!
Happy Learning :D
