For this is the love of God, that we keep his commandments. And his commandments are not burdensome. For everyone who has been born of God overcomes the world. And this is the victory that has overcome the world—our faith. – 1 John 5:3-5 ESV
Can you love God without obedience to him? John pretty clearly responds to that question saying that obedience to God is love for him. I cannot rightly claim to love God and blatantly disregard his instruction for my life. This is not to say that we will be perfect, but we should be striving towards obedience.
Lest you despair of being able to obey his commands, John assures us that obedience is not to hard for us, because our trust in God enables us to overcome the world and it’s pull on us.
Trust in the Lord with all your heart,
and do not lean on your own understanding.
In all your ways acknowledge him,
and he will make straight your paths.
