Barrier against temptations God's Judgement, and God's goodness (James 1:13-18)

"The mature person is patient in trials. Sometimes the trials are testing on the outside, and sometimes they are temptations on the inside. Trials may be tests sent by God, or they may be temptations sent by Satan and encourage by our own fallen nature. It's this second aspect of trials  - temptations on the inside - that James dealt with in this section." - Warren Wiersbe Be Mature on James 1:13-18

Trials are external events that test our faith for what it is, temptations are internal, how we respond to the trials.
Consider these three facts:
1. Consider God's judgment of our desire, plan and willful action (James 1:13-16)
 - Look ahead and see where sin ends - death. Paths Principle: Direction, not intention leads to destination
 - A temptation is an opportunity to accomplish a good thing in a bad way, out of the will of God. (Thinking of my desire for my brother's baptism that was canceled due to COVID-19. What does Baptism mean, why do it?)
We think of sin as a single act but sin has five stages
It starts with what we look at, then what we dwell on "lust" (Matt 5:28), this is desire (James 1:14). This desire is also coveting, marked by an inordinate desire for wealth or possessions or for another's possessions. Craving for possession covetous of power.

Some try and suppress hunger and desire, but this makes them less than human. Desires of life are the steam in the boiler that makes the machinery go. Turn off the steam and you have no power, let it go it's own way and you have destruction. The secret is in constant control. These desires must be servants not our masters, and this we can do through Jesus Christ.

 - Blessed are they who hunger and thirst for righteousness (Matt 5:6), mercy, purity, peacemakers (Matt 5:7-9). persecuted because of righteousness (people insult, persecute, falsely say all kinds of evil against us because of Jesus) - Matt 5:10-11

 - Deception in the intellect (James 1:14)
 - "drawn away" carries with it the idea of the baiting of a trap (Offense, separation, categorizing sin, fostering wounds, arguments, and worry). Yielding to the desire will eventually bring sorrow and punishment. The bait is an exciting thing.
 - Jesus was tempted by Satan and he always dealt with the temptation on the basis of the Word of God. Three times He said, "It is written." When you know the Bible you can detect the bait and deal with it decisively. This is what it means to walk by faith and not by sight.

 - Disobedience in the will (James 1:15)

We have moved from the emotions (desire) and the intellect (deception) to the will. James changed the picture from hunting and fishing to the birth of a baby. Desire conceives a method for taking the bait. The will approves and acts, and the result is sin. Whether we feel it or not, we are hooked and trapped. The baby is born, and just wait until it matures!

...Christian living is a matter of the will, not the feelings. This explains why immature Christians easily fall into temptation: They let their feelings make decisions. The more you exercise your will in saying a decisive no to temptation, the more God will take control o your life. "For it is God which worketh in you both to will and to do of his good pleasure (Phil 2:3)."

 -  Death is fully mature disobedience
God has erected this barrier because he loves us (Gen 2:17, Ezek 18:23). We see this all in the original sin. Eve saw nothing wrong with the knowledge or eating food (Gen 3:5), she saw it was good (Gen 3:6). Paul describes the deception in 2 Cor 11:3 as being beguiled by subtlety away from simplicity in Christ. Even (under Satanic deception) gave it to Adam (not directly deceived by Satan), his sin plunged the human race into tragedy (Romans 5:12-21; 1 Tim 2:12-15)
 - Death Through Adam, Life Through Christ (Romans 5:12-21)
 Dying without Jesus Christ a person will experience eternal death, the lake of fire (Rev 20:11-15)
 - God abolishes sin and death, creating a new heaven and earth (Rev 20:11-21:8)

2. Consider God's Goodness (James 1:17)

Satan wants us to think God is holding us back from good. Think again of Jesus temptation (Matthew 4), as to say "If the Father loves you, why are you hungry?" Since God is good, we don't need any other person to meet our needs. It is better to be hungry in the will of God than full outside the will of God. Moses warned Israel not to forget God's goodness when in the promised land (Deut 6:10-15). 

 - God gives only good gifts, even when we don't see it at first (Paul's thorn became a tremendous blessing to him 2 Cor 12:1-10)
 - God's way of giving is good. "and every act of giving" What He gives and how He gives are both good
 - He gives constantly. "Cometh down" is present participle: it keep on coming down.
  - God does not change. He is perfect in nature and character, so while it's impossible for God to change this He does change his mind.
