If that were the case, they would be striving for the goal from the same starting level. Why has God given people a different amount of faith?
Rom 12: 3 For I say, through the grace that was given me, to every man who is among you, not to think of himself more highly than he ought to think; but to think reasonably, as God has apportioned to each person a measure of faith.
1 Cor 12:11 But the one and the same Spirit works all of these, distributing to each one separately as he desires.
Mat 25:15 To one he gave five talents, to another two, to another one; to each according to his own ability. Then he went on his journey.
Rom 9:21 Or hasn’t the potter a right over the clay, from the same lump to make one part a vessel for honor, and another for dishonor? 2 Tim 2: 20 Now in a great house there are not only vessels of gold and of silver, but also of wood
The Spirit of God works all these things, distributing to each one individually just as God wills. God also has decided whom he calls and whom he selects and whom he draws unto Christ. Paul had no opportunity to refuse Christ’s call. Three days he was blind, without eating and drinking. Then the Lord’s enemy became his steadfast supporter. God works out his will. The person, who feels he hasn’t got as much as someone else, can find comfort in that God will remember him in the last judgment.
… God has allotted to each a measure of faith (Rom 12:3)
Why God did not give everyone as much faith but instead He gave a different measure? Rom 12:3 For by the grace given to me I ask every one of you not to think of yourself more highly than you should think, rather think of yourself with sober judgment on the measure of faith that God has assigned each of you.
1 Cor 12:11 But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
Rom 9:21 Does not the potter have power over the clay, from the same lump to make one vessel for honor and another for dishonor?
2 Tim 2:20 In a large house there are not only utensils made of gold and silver, but also those made of wood and clay. Some are for special use, while others are for ordinary use.
God distributes gifts as he wills, to each according to their capabilities. God has also decided who he calls and who he chooses and whom he is attracts to himself and to Christ. Paul did not have the opportunity to refuse Christ’s invitation. For three days he was blind, without eating and drinking. Then the enemy of the Lord became his steady advocate. God does his will. The man who feels that he has not received as much as some others can be comforted that God remembers him in the final judgment.
