My Father, which gave [them] me, is greater than all; and no [man] is able to pluck [them] out of my Father's hand. John 10:29
For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord. Romans 8:38-39
Submit yourselves therefore to God. Resist the devil, and he will flee from you. James 4:2
For the which cause I also suffer these things: nevertheless I am not ashamed: for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day. 2 Tim 1:12
[Let your] conversation [be] without covetousness; [and be] content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee. Hebrews 13:5
Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world 1 John 4:4
There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love. 1 John 4:18
However, it is possible to quench the Spirit (I Th 5:19) and therefore, we must choose to walk in His Light (1 John 1:7) to follow Him (Romans 8) to believe Him. We become at risk the very moment we fail to believe God.
The flight of the Israelis is an example. There they were, standing next to the Red Sea, quaking in fear of the mighty Egyptians who were pursuing them even though God had just performed ten mighty miracles in having them released. They didnt trust Him. Again, despite all that He had done in caring for them in their journey the scouts returning from the promised land all except for Caleb quaked in fear of the occupants and their fear spread throughout the camp. They didnt trust God and thus every single one of them died in the wilderness save Caleb and Joshua.
If we believe any thing or any one our own senses and reasoning included - over Him, we will sink or worse:
For some, when they had heard, did provoke: howbeit not all that came out of Egypt by Moses. But with whom was he grieved forty years? [was it] not with them that had sinned, whose carcases fell in the wilderness? And to whom sware he that they should not enter into his rest, but to them that believed not? So we see that they could not enter in because of unbelief. Hebrews 3:16-19
Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief. Heb 4:11
But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death. Rev 21:8
Alas, Some children of God do fear the monster under the bed, in a closet or as shadows on the walls..
Hardly, A-G. It would mean that our faith makes us righteous, blameless and sinless, immune to any temptation. It would mean we are as perfect as He is, for only He could not be tempted by the devil.
Spiritual pride is a dangerous delusion. Apostle Paul warns [my ephases]:
No wonder, for even Satan disguises himself as an angel of light.
Therefore it is not surprising if his servants also disguise themselves as servants of righteousness, whose end will be according to their deeds. [2 Cor 11:13-15]
