Why do we want to know and love God? Because we need Him. Being a part of this world is just too hard without Him. There is too much fear and pain to carry alone. I know that we have friends and family who are often there to help us when we need it, but let’s face it -- these people are human, which means they are not perfect. That also means that no matter how hard they try, or possibly don’t try, they will let us down sometimes.
There is no way that other people can meet all of our needs and it isn't really fair to expect them to. We are created by God and for God. That means that God is the only one who can give us all that we need. He gives us His unconditional love. We can turn to Him in all circumstances and He is there to encourage us, to heal us, to rejoice with us, and to love us. He is the perfect friend and He will never let us down if we trust in Him completely.
