A chapter by chapter verse by verse study in the book of Proverbs.
A burdened heart belongs to a person who is carrying their own sorrows or their own burdens. Jesus Christ said that He was a burdenbearer. He said, "If the load is heavy, you're carrying the wrong yoke." He said, "My yoke is easy, My burden is light." Matthew 11:30 He is not only a sin bearer, He is a burden bearer, too." He wants to carry the load. He wants to be that burden bearer for you so that you can be of a cheerful countenance. Christians don't really have an excuse. Sometimes we get under the circumstances but we don't have an excuse to be there. We are exhorted time after time after time that the Lord has allowed trials to come into our life to perfect us, to renew us, to strengthen us, to mold us, shape us and make us like Him. We don't need to be burdened down. He said, "In this world we can expect trials." But He says, "But be of good cheer, I have overcome the world." John 16:33. If I choose to be sorrowful, my heart will slump and crumple. I am learning to hand things over to Him and letting Him carry the load.
