We read in the book of Matthew there is a wide gate which leads to destruction,and a strait (narrow) gate that leads to life. The distinction between the two is there are many more going through the wide gate and only a few are going through the strait one. The depiction of the two gates are the choices we make that leads us to life (eternal) or death (hell).
Scripture teaches it is not easy to enter the narrow gate and that we must strive to enter it!
STRIVE – To devote serious effort or energy,to struggle in opposition,to contend,endeavour.
Jesus gives us a better answer when one posed the question to Him “Lord,are there few that be saved?” and His reply allows us to see how many believe they are doing just fine (Luke 13:23-30) 23 Then said one unto him, Lord, are there few that be saved? And he said unto them, 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. 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. 29 And they shall come from the east, and from the west, and from the north, and from the south, and shall sit down in the kingdom of God. 30 And, behold, there are last which shall be first, and there are first which shall be last.
Did you see the answer given in verse 27 as to why the door is shut unto us and we would not be allowed to enter heaven? It is our sin that keeps us out. (Isaiah 59:1-4) 1 Behold, the LORD’S hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear: 2 But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear. 3 For your hands are defiled with blood, and your fingers with iniquity; your lips have spoken lies, your tongue hath muttered perverseness. 4 None calleth for justice, nor any pleadeth for truth: they trust in vanity, and speak lies; they conceive mischief, and bring forth iniquity.
It is up to us to choose the gate that leads to life or enter the gate that leads to destruction and hell. A way that is never full for sadly so many choose! (Proverbs 27:20) 20 Hell and destruction are never full; so the eyes of man are never satisfied.(Proverbs 14:12).
