Where to find scriptural help, regarding doubt:
“Lord, if it’s you,” Peter replied, “tell me to come to you on the water.”
“Come,” he said. Then Peter got down out of the boat, walked on the water and came toward Jesus.
But when he saw the wind, he was afraid and, beginning to sink, cried out, “Lord, save me!” Immediately Jesus reached out his hand and caught him. “You of little faith,” he said, “why did you doubt?”
Lord God, you are always faithful. In your Word you tell us of your love that is ours through Jesus, and you promise never to leave us or forsake us, but to work all things for our good. Since you are faithful, lead us with these promises to trust you more and more, that doubts may not trouble our minds. Help us to be confident in you. Through Christ, our Lord. Amen.
Where to find scriptural help, regarding excuses:
When one of those at the table with him heard this, he said to Jesus, “Blessed is the man who will eat at the feast in the kingdom of God.”
Jesus replied: “A certain man was preparing a great banquet and invited many guests. At the time of the banquet he sent his servant to tell those who had been invited, `Come, for everything is now ready.’
“But they all alike began to make excuses. The first said, `I have just bought a field, and I must go and see it. Please excuse me.’
“Another said, `I have just bought five yoke of oxen, and I’m on my way to try them out. Please excuse me.’
“Still another said, `I just got married, so I can’t come.’
“The servant came back and reported this to his master. Then the owner of the house became angry and ordered his servant, `Go out quickly into the streets and alleys of the town and bring in the poor, the crippled, the blind and the lame.’
“`Sir,’ the servant said, `what you ordered has been done, but there is still room.’
“Then the master told his servant, `Go out to the roads and country lanes and make them come in, so that my house will be full. I tell you, not one of those men who were invited will get a taste of my banquet.'”
