What ark are you trying to build? The Lord says your works are as dirty rags.
God has already provided His Sacrifice. God Provides. We have faith in His Provision. We ask and we receive.
We don't build. Its already built. It is Finished!!!
Hallelujah
Jesus taught those who were considering to follow Him ought to count the cost.
Luk 14:26 If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple.
Luk 14:27 And whosoever doth not bear his cross, and come after me, cannot be my disciple.
Luk 14:28 For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it?
Luk 14:29 Lest haply, after he hath laid the foundation, and is not able to finish it, all that behold it begin to mock him,
Luk 14:30 Saying, This man began to build, and was not able to finish.
Luk 14:31 Or what king, going to make war against another king, sitteth not down first, and consulteth whether he be able with ten thousand to meet him that cometh against him with twenty thousand?
Luk 14:32 Or else, while the other is yet a great way off, he sendeth an ambassage, and desireth conditions of peace.
Luk 14:33 So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple.
Jesus didn't imply in His teaching above that everything was built already. The implication is that you have to do something.
What might that be?
Simply it is being a doer of the word. Those who are the doers BUILD their house upon the rock.
Mat 7:24 Therefore
whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
Mat 7:25 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
Mat 7:26 And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:
Mat 7:27 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.
Jesus Christ is the foundation that we build upon.
When Jesus said it is finished He was referring to the propitiatory sacrifice on the cross on behalf of our past sins (Rom 3:25). He still had to be resurrected, people still had to follow Him.
So you honestly believe that "it is finished" cancels out "striving" and patiently continuing?
Striving...
Luk 13:23 Then said one unto him, Lord, are there few that be saved? And he said unto them,
Luk 13:24 Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able.
Patiently continuing...
Rom 2:7 To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
Paul sure didn't think "it is finished" applied to running the race with endurance.
1Co 9:24 Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain.
1Co 9:25 And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible.
1Co 9:26 I therefore so run, not as uncertainly; so fight I, not as one that beateth the air:
1Co 9:27 But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.
Even after "It is finished" Jesus said this..
Mat 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
Mat 28:20
Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
