Ps. 24:3-4 Who may climb the mountain of the LORD? Who may stand in his holy place? Only those whose hands and hearts are pure, who do not worship idols and never tell lies.
A mountain is a very tough thing to climb. In order to get to the top one must persevere. Depending on one's physical condition, there is a great price to pay. It takes a lot of time and effort. A mountain is full of very difficult terrain. There are a lot of known and unknown dangers. Only those who have the will to get to the top will make it. The way to the Lord is just like a mountain climb.
There is great exhileration for those who make it to the top and stand. There is nothing quite like persevering and winning. Reaching the top is a job well done. To have a goal in mind and achieve it is good for the soul. The ultimate goal of every believer should be holiness of heart.
Holiness can only be achieved by those who have pure hearts. There has to be a desire to not sin. There has to be effort put into not sinning. There has to be effort put into staying spiritually fit. There has to be effort put into obeying the Word of God. There has to be more than talk; there has to be a walk as well.
God is not unaccessable. He is found by all who sincerely seek Him. The road can be very rough at times and only those who persevere will make it. There will be much stumbling along the way and perhaps much pain and suffering. In order to reach God, we must keep our eyes focused on Jesus and never leave His protective care.
