We might be tempted to read Leviticus 26 and hear how God promises blessing for obedience and punishment for disobedience and simply relegate such notions in our minds to some obsolete “Old Testament” box that does not apply any more. We now live in the New Covenant, we might subconsciously think. This blessing being contingent on obedience deal no longer applies we might assume. Let us beware of doing so!
Obedience is still required under the New Covenant even though some of the stipulations to be obeyed have been changed. The reason behind this is that the New Covenant brings with it a new nature for its recipients! And though we will not attain perfection until Jesus comes there will be some degree of transformation. Any other alternative is completely unthinkable to the New Testament authors.
So strive to obey, by the grace of God, today!
