Beloved, God tests us to refine us and consecrate us for him in order that we may be closer to him, and that God may be glorified in us.
And I will bring the third part through the fire, and will refine them as silver is refined and will test them as gold is tested. They will call on My name, and I will hear and answer them. I will say, It is My people; and they will say, The Lord is my God.
God, like a good Father, will not let us fall too far into a hopeless state through his trials. Take money, for example. If we covet money, God will not bless us financially. He will do what is necessary to show us that we need to surrender this part of our lives to Him, to refine us of this covetous desire, but will not, for example, let us fall into a severe hopeless state of poverty, i.e. something that we are not capable of handling or escaping.
For no temptation (no trial regarded as enticing to sin), [no matter how it comes or where it leads] has overtaken you and laid hold on you that is not common to man [that is, no temptation or trial has come to you that is beyond human resistance and that is not adjusted and adapted and belonging to human experience, and such as man can bear]. But God is faithful [to His Word and to His compassionate nature], and He [can be trusted] not to let you be tempted and tried and assayed beyond your ability and strength of resistance and power to endure, but with the temptation He will [always] also provide the way out (the means of escape to a landing place), that you may be capable and strong and powerful to bear up under it patiently.
1 Cor 10:13 -- See also NIV translation
The difference in being led astray by the devil in his temptation is a blurry line for me, so sorry if this is not correct (please correct me), but there is a difference. When we give ourselves over to sin, and do not heed to God's conviction and repent, we fall away from God. But if we are truly God's and have real faith in him, we should not intentionally do this. I believe these kinds of people are defined in Matthew 13:7&22:
Other seeds fell among thorns, and the thorns grew up and choked them out.
As for what was sown among thorns, this is he who hears the Word, but the cares of the world and the pleasure and delight and glamour and deceitfulness of riches choke and suffocate the Word, and it yields no fruit.
Given the text, these people are probably not truly God's. But only God knows.
But the gate is narrow (contracted by pressure) and the way is straitened and compressed that leads away to life, and few are those who find it.
Beware of false prophets, who come to you dressed as sheep, but inside they are devouring wolves.
You will fully recognize them by their fruits. Do people pick grapes from thorns, or figs from thistles?
Even so, every healthy (sound) tree bears good fruit [worthy of admiration], but the sickly (decaying, worthless) tree bears bad (worthless) fruit.
