Genesis 26:12-13
12And Isaac sowed in that land and reaped in the same year a hundredfold. The LORD blessed him, 13and the man became rich, and gained more and more until he became very wealthy. 14He had possessions of flocks and herds and many servants, so that the Philistines envied him.

It is not a coincidence that this passage points out that Isaac became very rich (Verses 12-17). His obedience was blessed by God. It would be foolish and a contradiction of the great weight of Scripture to conclude from this that obedience always makes one rich. But it is wise to conclude that obedience always will result in blessing from God. That blessing may be long in coming, and it may be material, spiritual, physical or all of those.

The biggest and most satisfying of these will be the inner peace, the joy, the communion with God that a child of God knows when he is in a state of obedience. And those things will be his even in the midst of great difficulties in life. Obedience will always reap great blessing in the life to come.

The promise of blessing is meant to be a great incentive to us to obey. All of the commandments of God are accompanied by a promise to the obedient. The degree to which we believe the promise is marked by the degree to which we obey the command. It is the height of sin to call upon God to keep His promises if we are not in obedience to the conditions He has set.

Do not rob yourself today of the immense blessing of God in your life. Know the joy of obedience to God. Use all He gives you to triumph over sin.
