Keep the door open.
God wills that all men be saved and come to a knowledge of the truth. So God's purpose for your life is to go to heaven and to help others to go to heaven. Jesus warns the Scribes and Pharisees because not only are they not going to heaven but they are hindering others from going as well. If we love God we will accept God gift of salvation and we will help others to enter heaven as well. What ever we do for God, for the Church, for others we should do from the motive of love and not simply self interest. Only by following Jesus Christ crucified is this possible. If any man would come after me, take up his cross and follow me. If you do not do penance you will surely perish. Jesus is calling you to come follow him and to help others to enter heaven as well. Proclaim his love!
13 But woe to you scribes and Pharisees, hypocrites; because you shut the kingdom of heaven against men, for you yourselves do not enter in; and those that are going in, you suffer not to enter.
14 Woe to you scribes and Pharisees, hypocrites: because you devour the houses of widows, praying long prayers. For this you shall receive the greater judgment.
15 Woe to you scribes and Pharisees, hypocrites; because you go round about the sea and the land to make one proselyte; and when he is made, you make him the child of hell twofold more than yourselves.
16 Woe to you blind guides, that say, Whosoever shall swear by the temple, it is nothing; but he that shall swear by the gold of the temple, is a debtor.
17 Ye foolish and blind; for whether is greater, the gold, or the temple that sanctifieth the gold?
18 And whosoever shall swear by the altar, it is nothing; but whosoever shall swear by the gift that is upon it, is a debtor.
19 Ye blind: for whether is greater, the gift, or the altar that sanctifieth the gift?
20 He therefore that sweareth by the altar, sweareth by it, and by all things that are upon it:
21 And whosoever shall swear by the temple, sweareth by it, and by him that dwelleth in it:
22 And he that sweareth by heaven, sweareth by the throne of God, and by him that sitteth thereon.
23 Woe to you scribes and Pharisees, hypocrites; because you tithe mint, and anise, and cummin, and have left the weightier things of the law; judgment, and mercy, and faith. These things you ought to have done, and not to leave those undone.
