Our hearts are very important to God because He does not see as man does, for man looks on the outward appearance and He looks on the heart.(1 Samuel 16:7). But the Lord said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for the Lord seeth not as man seeth; for man looketh on the outward appearance, but the Lord looketh on the heart.
Our heart is the center of all emotion and Jesus said out of the heart a man speaks. When a loved one dies our heart is heavy and filled with sorrow and grief and we feel the pain, while at a joyous occasion our heart feels light. (Luke 6:45). A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh……. (Proverbs 12:25….. 15:15)….. (Psalm 5:10-12).
God understands our heart like no other and He like us has many emotions, we see this when He was sore grieved at His heart after seeing man’s heart was continually set on evil. (Genesis 6:5,6).
We have heard the phrase they are a person after my own heart, but did you know this saying goes way back and was spoken long ago when after forty years Saul was king and David reigned in his stead saying “He is a man after mine own heart”. (Acts 13:20-22). And after that he gave unto them judges about the space of four hundred and fifty years, until Samuel the prophet. And afterward they desired a king: and God gave unto them Saul the son of Cis, a man of the tribe of Benjamin, by the space of forty years. And when he had removed him, he raised up unto them David to be their king; to whom also he gave their testimony, and said, I have found David the son of Jesse, a man after mine own heart, which shall fulfil all my will.
It is written that as part of Gods New Covenant with man He will put His laws in our hearts and write them in our mind, and by doing so it would be hard to not serve Him! (Hebrews 10:15-17)…… (Isaiah 51:7).
