Obedience in the normal dictionary means: ' To submit your own will to the will of someone else and act according that will.'
Obedience in the biblical way means: 'To submit your own will to the will of God and to act according God's will.'
In normal life it is hard to submit your will to the will of someone else, unfortunately it is the same with the Lord Romans 8:7 (NIV) The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so.
There are a few things you can do that will help you to obey the Lord:
1. You have to accept Christ:
Because of Christ we can get a relationship with God and you need some kind of relationship with someone before you can truly obey them. Jesus is God so by loving Jesus and doing what He asks you to do you are obeying God
John 14:23(NIV) Jesus replied, “Anyone who loves me will obey my teaching. My Father will love them, and we will come to them and make our home with them.
2. You have to get to know God's will:
It is hard to obey someone if you don't know what he wants from you. The main way you can get to know God's will is through the word. It is something I truly love to do. The word is like God's thoughts, it has everything we need. It has the answers and of course God's will in it. An exapmle is Micah 6:8(NIV) He has shown you, O mortal, what is good. And what does the Lord require of you? To act justly and to love mercy and to walk humbly[a] with your God. Here you can see clearly what the Lord wants of us. It is really important for a christian to read the word of God (Joshua 1:8, psalm 119:105). A second way is to pray, God often answers through prayer by a thought of an feeling.
