"If relationships are so good and necessary why are they so hard and frustrating?"

1 In the beginning, God created the heavens and the earth. 2 The earth was without form and void, and darkness was over the face of the deep. And the Spirit of God was hovering over the face of the waters. 3 And God said, “Let there be light,” and there was light. 4 And God saw that the light was good.
Genesis 1:1-4

26 Then God said, “Let us make man in our image, after our likeness. And let them have dominion over the fish of the sea and over the birds of the heavens and over the livestock and over all the earth and over every creeping thing that creeps on the earth.”27 So God created man in his own image, in the image of God he created him; male and female he created them.28 And God blessed them. And God said to them, “Be fruitful and multiply and fill the earth and subdue it, and have dominion over the fish of the sea and over the birds of the heavens and over every living thing that moves on the earth.”
Genesis 1:26-28

And God saw everything that he had made, and behold, it was very good. And there was evening and there was morning, the sixth day.
Genesis 1:31

18 Then the Lord God said, “It is not good that the man should be alone; I will make him a helper fit for him.” 19 Now out of the ground the Lord God had formed every beast of the field and every bird of the heavens and brought them to the man to see what he would call them. And whatever the man called every living creature, that was its name. 20 The man gave names to all livestock and to the birds of the heavens and to every beast of the field. But for Adam there was not found a helper fit for him. 21 So the Lord God caused a deep sleep to fall upon the man, and while he slept took one of his ribs and closed up its place with flesh. 22 And the rib that the Lord God had taken from the man he made into a woman and brought her to the man. 23 Then the man said,“This at last is bone of my bones and flesh of my flesh; she shall be called Woman, because she was taken out of Man.” 24 Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh. 25 And the man and his wife were both naked and were not ashamed.
Genesis 2:18-25

We were designed for relationship:

With Our Creator
With Each Other
With the Rest of Creation

8 And they heard the sound of the Lord God walking in the garden in the cool of the day, and the man and his wife hid themselves from the presence of the Lord God among the trees of the garden. 9 But the Lord God called to the man and said to him, “Where are you?” 10 And he said, “I heard the sound of you in the garden, and I was afraid, because I was naked, and I hid myself.” 11 He said, “Who told you that you were naked? Have you eaten of the tree of which I commanded you not to eat?” 12 The man said, “The woman whom you gave to be with me, she gave me fruit of the tree, and I ate.” 13 Then the Lord God said to the woman, “What is this that you have done?” The woman said, “The serpent deceived me, and I ate.”
Genesis 3:8-13

15 I will put enmity between you and the woman, and between your offspring and her offspring; he shall bruise your head, and you shall bruise his heel.” 16 To the woman he said,“I will surely multiply your pain in childbearing; in pain you shall bring forth children.Your desire shall be contrary to your husband, but he shall rule over you.”

Genesis 3:15-16

Sin impacts every relationship

Jesus restores relationship
