“Because narrow is the gate and difficult is the way which leads to life, and there are few who find it.”-Matthew 7:14 NKJV
Jesus never said life would be easy. In fact He said difficult is the way which leads to life. When we run into a difficult situation which seems impossible often our instinct is to run away, but the only running we should be doing is straight to God for help. This is living by faith. When we turn to Him in impossible situations He works through us and makes them possible. David did not run from Goliath.
“Then David said to the Philistine, “You come to me with a sword, with a spear, and with a javelin. But I come to you in the name of the LORD of hosts, the God of the armies of Israel, whom you have defied.” -I Samuel 17:45 NKJV
