God uses delays to test our obedience and patience.. 1Sam13

Rather than waiting for a priest, Saul offered the sacrifice himself. This was againts God's laws. Under pressure from the approaching Philistines, he took matters into his own hands and disobeyed God. He was doing a good thing , but he did it in the wrong way. 

Like Saul, our true spiritual character is revealed under pressure. The methods we use to accomplish our goals are as important as the attainment of those goals.

It is difficult to trust God when you feel your resources slipping away. When Saul felt that the time was running out, he became impatient with God's timing. In thinking that the ritual was all he needed, he substituted the ritual for faith in God. 

When faced with a difficult decision, dont allow impatience to drive you to disobey God. When you know what God's wants, follow HIS plan regardless of the consequences. God often uses delays to test our obedience and patience.

Saul had plenty of excuses for his disobedience. But Samuel zeroed in on the real issue. "you have not kept the command the Lord your God gave you". Like Saul, we often gloss over our mistakes and sins, trying to justify our actions because of our 'special' circumstances. Our excuses, however, are nothing more than disobedience. 

God knows our true motive, HE forgives, restores, and blesses only when we are honest about our sins. By trying to hide his sins behind excuses, Saul lost his kingship.
