Luke 14

There are three parables the Savior taught I read this morning that have a central theme.  First -

"A certain man had a fig tree planted in his vineyard; and he came and sought fruit thereon, and found none.
7 Then said he unto the dresser of his vineyard, Behold, these three years I come seeking fruit on this fig tree, and find none: cut it down; why cumbereth it the ground?
8 And he answering said unto him, Lord, let it alone this year also, till I shall dig about it, and dung it:
9 And if it bear fruit, well: and if not, then after that thou shalt cut it down."  (New Testament | Luke 13:6 - 9)

This parable suggest that there is more required than just being a professed believer, you must bear fruit.

The second parable reflects those that do not keep God's commandments and bring forth fruit.  We must -

"Strive to enter in at the strait gate: for many, I say unto you, will seek to enter in, and shall not be able.
25 When once the master of the house is risen up, and hath shut to the door, and ye begin to stand without, and to knock at the door, saying, Lord, Lord, open unto us; and he shall answer and say unto you, I know you not whence ye are:
26 Then shall ye begin to say, We have eaten and drunk in thy presence, and thou hast taught in our streets.
27 But he shall say, I tell you, I know you not whence ye are; depart from me, all ye workers of iniquity.
28 There shall be weeping and gnashing of teeth, when ye shall see Abraham, and Isaac, and Jacob, and all the prophets, in the kingdom of God, and you yourselves thrust out."  (New Testament | Luke 13:24 - 28)

This suggests to me that to enter into the gate, one must enter into covenants and ordinances, and keep them.  Just attending Church or "being taught" is not sufficient.

The last parable requires that we accept the invitation to come unto Christ, learn His doctrine, make and keep sacred covenants, receive His saving ordinances and keep His commandments as the Savior taught -

"...A certain man made a great supper, and bade many:
17 And sent his servant at supper time to say to them that were bidden, Come; for all things are now ready.
18 And they all with one consent began to make excuse. The first said unto him, I have bought a piece of ground, and I must needs go and see it: I pray thee have me excused.
19 And another said, I have bought five yoke of oxen, and I go to prove them: I pray thee have me excused.
20 And another said, I have married a wife, and therefore I cannot come.
21 So that servant came, and shewed his lord these things. Then the master of the house being angry said to his servant, Go out quickly into the streets and lanes of the city, and bring in hither the poor, and the maimed, and the halt, and the blind.
22 And the servant said, Lord, it is done as thou hast commanded, and yet there is room.
23 And the lord said unto the servant, Go out into the highways and hedges, and compel them to come in, that my house may be filled.
24 For I say unto you, That none of those men which were bidden shall taste of my supper."  (New Testament | Luke 14:16 - 24)

Again, it is apparent that there are conditions that must be satisfied or we shall not taste of His supper.  We can't just acknowledge or profess that Jesus is the Christ claiming to accept Him.
