Each act of obedience will be an extra encouragement and an extra sense of experiencing God. Those who are on the adventure and journey of faith know what it is regularly to have God's encouragements coming alongside you. Oh yes, there are difficult days. Perseverance is required. Paul the apostle knows all about this.
Success is a little like wrestling a gorilla.
The principles of human success apply in the spiritual life too, that we must persevere and not give up. But the Christian has an extra source of strength which is the very relationship we seek to grow in. So as you commit yourself to God, as you obey God, so that connection already established, that communication all very vibrant, will also be strengthened and upheld. So Saul must go to the City. Even though like Abraham he cannot see where he is going.
