...heaviness through manifold temptations. I Pet. 1:6

Now for a season, if need be, ye are in heaviness through manifold temptations. I Pet. 1:6

I think, '...and lead us not into temptation...', but this is not temptation to sin, but testing through adversity, which builds patience/endurance in our lives.

Beloved, think it not strange concerning the fiery trial which is to try you, as though some strange thing happened unto you: but rejoice, inasmuch as ye are partakers of Christ's sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy. I Pet. 4:12, 13

I feel I have yet to cultivate an immediate response or prolonged response of 'rejoicing'.

The exhortation ... speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him. Heb. 12:5

I must watch my attitude towards chastening and rebuke...

Now no chastening for the present seemeth to be joyous, but grievous: nevertheless, afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby. Heb. 12:11

There is the reality that chastening hurts--it bites, stings, wounds--but we have hope as His children that it is not punishment, but fruit-bearing chastening.

We have not a high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin. Heb. 4:15

For in that he himself hath suffered being tempted, he is able to succour them that are tempted. Heb. 2:18

God is faithful, who will not suffer you to be tempted above that ye are able. I Cor. 10:13
