As a child of God, complaining over any given issue/ challenge does not solve it but rather makes it worse. The opening scripture is vivid to the fact that every child of God is prone to temptation. If Jesus Christ went through it, we will also go through it. Hallelujah! Instead of complaining and feeling frighted, look for the way of escape which God has provided in the midst of the temptation so that you will be able to overcome it as Jesus did, Matthew 4:1-11.
We have been given the assurance that the temptation is within our scope of abilities to overcome; therefore, if you fall as a Christian in the midst of temptation, quickly get up and look for the way of escape in the Holy Scriptures and overcome the temptation. There is a second chance for you to rewrite your failure into success. Praise the Lord!
