But the Lord is faithful. He will establish you and guard you against the evil one.
2 Thessalonians 3:3
Life brings us various types of difficulties, of different levels. Some are hard to solve while some only take time. For instance, addiction. When a person is addicted, may it be to computer games, to pornography, to eating, selfies, etc., there is the willingness to quit but the force of temptation is so strong. At the end of the day, the person will succumb to the will of the flesh. Another example is the problems we face in every step of the way. There are times when the enemy will discourage you. People will throw negative comments about you and your situation. And if you are weak, you might believe them.
Temptation comes from the flesh of man. As long as a man is in the flesh. There is the presence of temptation to sin. The spirit must be allowed to overcome the flesh. So, when we are tempted to surrender to our addiction, we know now what to do. We must allow the Spirit of Christ within us to be our Lord and guide us in everything. The Spirit will overcome the flesh and keep us from evil.
There are many who do not have faith in the Lord. These are people who speak what is opposed to the word of God. Be still. God is keeping His promises for He is faithful. When you have a problem, pray! God will guard you against the evil one. Choose wisely to whom you will voice out your concern because if you confess it with the wrong person, you might be doomed to something worse than your problem.
