2 Clem. 11
Let us therefore serve God in a pure heart, and we shall be righteous; but if we serve Him not, because we believe not the promise of God, we shall be wretched.
2Clem 11.1
For the word of prophecy also saith: Wretched are the double-minded, that doubt in their heart and say, These things we heard of old in the days of our fathers also, yet we have waited day after day and seen none of them.
2Clem 11.2
Ye fools! compare yourselves unto a tree; take a vine. First it sheds its leaves, then a shoot cometh, after this a sour berry, then a full ripe grape.
2Clem 11.3
So likewise My people had tumults and afflictions: but afterward they shall receive good things.
2Clem 11.4
Wherefore, my brethren, let us not be double-minded but endure patiently in hope, that we may also obtain our reward.
2Clem 11.5
