What if God never speaks to us or gives us instructions through His words? It would be disaster unimaginable for us. So I submit that we are blessed two-fold 1. In receiving His word and 2. When God performs the words we receive from Him. Be confident that God never fails neither does His word produce nothing. So if you receive His word, no matter what things seem or feel like, hold on to His words until you see your change come. Leviticus 19 and 20 touch on similar things and have many instructions we must follow. If we do, these 2 results below will be ours; an increased harvest and God making us holy (read Lev. chapter 19 and 20 for full context).
Leviticus 19:25b
…In this way your harvest will be increased. I am the Lord your God.
Leviticus 20:7-8
7 “‘Consecrate yourselves and be holy, because I am the Lord your God.
8 Keep my decrees and follow them. I am the Lord, who makes you holy.
