What are we doing?

Pastor asked a question Sunday.
What hinders us, stops us from reaching for the promise and reaching the promised land?
The promise here on earth and the promised land as in Heaven.
It should be a short journey, but it takes us so many years.

Increduility, skepticism, unbelief in the Lord and Jesus Christ.
Lack of faith, being disloyal, unworthy, not observing the covenant/promise.
Unwillingness to submit, be humble, too much pride and arrogance, self-righteousness.
Our transgressions, sin of omission/commission, violation of God's Will/Law.
Not being sincere, inconsistant.
Do not trust in the Word, doubt, uncertainity, hesitation.
Not wanting to give God the credit, willful disobedience, deliberate wickedness.
Unable to make the required adjustment, to depend on the Lord.
No trust in the truth of the actual existence of a Lord and Savior.

The Lord's promise, what kept/keeps you from reaching for it?
