Our zeal for the Lord should always be in line with the clear direction of the Lord.
When we face trials and tribulations we need to have the same faith in God that Jesus had in the Father.
If a man feels led to preach the gospel, he should consider this lesson and be in deep prayer and preparation before he even begins to answer that call. He should continue in prayer and preparation while he carries out God's orders. And it would be a true help to the cause of Christ if his church and family freed his hands as much as possible to the good work.
"Whoever may came next, Christ must be first!" – Spurgeon
Jesus was homeless so that we could have an eternal mansion in glory!
Jesus did not say it was difficult to serve God while holding onto the world. He said we CANNOT serve God and mammon (Matthew 6:24).
The disciples thought the command to forgive was to difficult, so they asked for more faith. Jesus basically says you have the faith, use it. And in the end, just realize that you are only doing what you were told to do.
If we require more of another person than Christ required of us then we are asking too much.
I think one of the greatest liberties to be found is when we admit that we are so small and tiny compared to God.
When we are humble and the kingdom advances, it is clear that only God should receive the glory!
