Ps 31 5 Into your hands I commit my spirit;
redeem me, O LORD , the God of truth".
The Psalmist is making a confession to unite his trust in Gods refuge. Gods refuge is resting in Christ righteousness. The Psalmist believes that Gods righteousness is successful over all opposition because He is the Rock of Israel. The Rock of Israel is the commander of Israels armies. He is always successful in winning Israels wars. Gods kingdom on earth is established by God carrying out His law over the nations.

This is what the Psalms means by standing in Gods righteousness. He is totally secure within the walls of Jerusalem. Because God cannot be thwarted the Psalmist expresses his trust in God by the petition to prevent him from the trap of those who oppose Gods kingdom. This trap is being threatened and captured by his accusers. He has pronounced Gods laws, decrees, covenants, curses and promises that bring about Gods recreation of the Psalmist experience. This means that the Psalmist has encountered opposition. The world is a place when we stand for something we are opposed. There is no peace in a sinful and corrupt world. This opposition is always voiced in the atheistic pronouncement of he trust in God, let God deliver him. The humanist is saying that Gods silence is proof that God does not exist. They are always tempting the christian to put their trust in other gods.
This is the sword that the opposition uses to give Gods people a mortal wound. The Psalmist believes that there is a conspiracy that is natural in a corrupt world. If all men were perfect then they would promote Gods purposes by example. But every time a person sins they place an obstacle in the way of Gods purposes.Out of this natural communication comes these conspiracies. This is why sometimes you see a new born Christian whos trust is more pure and genuine than a mature christian. The fact that the mature christian does not rise up to the genuineness of his confession is like a stumbling block to the new born.This shows us that our growth must come as a result of extreme effort to kill anything that causes us to lose touch with our first love. Cursing is so extreme that we are always brought back to that first freedom.
We should always be able to find the christian attitude that the scripture encourages as a matter of discipline. In other words if there is rejoicing we should be able to display that by our control over our hearts. And if it is sorrow we should be able to control that so that we can be of help to those new Christians. Whatever they display as genuine because it is new should be greater under our mature control. So the Psalmist is confessing the way to overcome all opposition and sealing it by giving himself into Gods hands. This is emptying ourselves in the christian life.
