Why is it often difficult for us to demonstrate immediate obedience to God's instructions?

Answer 1

Inherited Sin from Adam: "That is why, just as through one man sin entered into the world and death through sin, and so death spread to all men because they had all sinned" (Romans 5:12)

Our own Hearts: "The heart is more treacherous than anything else and is desperate. Who can know it?" (Jeremiah 17:9)

Pressure from the Devil and his world: "We know that we originate with God, but the whole world is lying in the power of the wicked one." (1 John 5:19)

Answer 2

We are created with an evil inclination. This causes an initial thought of "No!" when we're told to do something, no matter who the request comes from. The thought of "maybe" or "yes" comes only after that, if at all.

In addition:

1) Peer influence; hearing ridicule. We may have heard irreverent tidbits, jokes, and "sound-bites" which make it difficult to take religious responsibilities seriously.

2) Convenience; desires. No one wants "bothersome" rules, or limitations to their personal pleasure. We see how lack of self-discipline and the desire for pleasure has led to epidemic obesity, drunkenness, divorce rates, violence etc.

3) Lack of proper information. We might have incomplete knowledge about God.

4) Unfortunate experiences. We might have had personal hardships, or a harsh religious upbringing or education, and as a consequence may retain an unhappy feeling towards belief.

5) We might think that science, and specifically Evolution, have proved that there is no God. We need to realize that even if Evolution was an unquestionable fact, it would not automatically follow that God isn't there.

6) Intellectual laziness. Maybe we never delved deeply into the subject, to see if God's existence and authority can be convincingly demonstrated.

7) Stereotyping. People call us "religious nuts," "Bible-thumpers," etc.; so we might have picked up a negative undercurrent toward all belief.

Answer 3

Because no one has or can define what god is. There are many of them with different instructions, which makes it difficult to choose which ones to obey.
Your local cleric, shaman or vicar will insist their god is the 'real' one but none of them can prove it so.
You should build your own set of ethics and morality suitable for the society in which you reside with guidance from those you have respect for. Another persons rules may not apply to you.
