Has God asked you to do something that you have not followed through on? What is stopping you? Could it be fear? Could it be that you cannot understand why God is possibly asking you to do whatever it is that He is requesting of you. Or maybe you could have doubts that He has in fact asked you to do this particular request.
When God requested Moses to lead His chosen people out of Egypt, even Moses had doubts that he could not handle the responsibility. He replied to God, “Who am I that I should go to Pharaoh and bring the Israelites out of Egypt?” (Exodus 3:11)
Sometimes being obedient to God’s requests can bring out our insecurities.  Like Moses he was not trying to be disobedient, his concern was that he didn’t think that he was up to the challenge.  We have to keep in mind that God has equipped us to do whatever it is that He asks of us.
Being obedient means to walk in faith, it means that we are willing to trust that God has a plan for our life that is only meant for good. As we continue to trust in Him, our relationship grows stronger and we continue to learn just how important obedience can be.
King David shares with us in Psalms 119 a few verses on obedience. I have included part of Psalms 119 below.
Blessed are those whose ways are blameless,
who walk according to the law of the Lord.
Blessed are those who keep his statutes
and seek him with all their heart—
they do no wrong
but follow his ways.
You have laid down precepts
that are to be fully obeyed.
Oh, that my ways were steadfast
in obeying your decrees!
Then I would not be put to shame
when I consider all your commands.
I will praise you with an upright heart
as I learn your righteous laws.
I will obey your decrees;
do not utterly forsake me.
How can a young person stay on the path of purity?
By living according to your word.
10 I seek you with all my heart;
do not let me stray from your commands.
11 I have hidden your word in my heart
that I might not sin against you.
12 Praise be to you, Lord;
teach me your decrees.
13 With my lips I recount
all the laws that come from your mouth.
14 I rejoice in following your statutes
as one rejoices in great riches.
15 I meditate on your precepts
and consider your ways.
16 I delight in your decrees;
I will not neglect your word.
