This verse helps explain why there were all these guidelines, consequences, etc. Israel was to be separate/different from the people around them to receive the blessings God had for them. God wanted a nation of people who would walk in holiness. Thus all the things listed, including homosexuality, were the opposite of holiness.
Some of the guidelines may not make sense to us, but the underlying principle was for the priests to walk in holiness.
The priests were to be careful how they handle the offerings. Today, pastors need to be careful how they handle tithes and offerings.
The disciples could not grasp the concept that Jesus was going to die, which means they had no concept of Him being raised from the dead. Is there things that God hints at to us but we do not grasp what He is saying? Maybe there are promises He has gien us but we do not see how they can happen.
The disciples could not cast out the demon, we find out why in vs 29.
The father had some doubt if Jesus could heal his son(because others had prayed for him and nothing changed). The man asked Jesus to help him overcome his unbelief. Because of past experiences we my have unbelief, lets ask Jesus to help us overcome our unbelief.
Most Bibles have prayer and fasting. However in the original Greek, the word fasting is not there. It is obvious that Jesus was saying serious prayer needs to take place. If we are seriously praying about something there will probably be some fasting taking place also.
God is on our side (if we are walking in integrity and purity) even when we feel like He isn’t.
We should walk in integrity and honesty-not be phony
