The only true way to keep God's commandments is to accept Jesus Christ as Saviour. When you do this, Jesus gives you His Own righteousness. However, the context indicates that Solomon means that we are to live lives of continual obedience to God.
Joh 14:21 He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.
One of the great blessings of obedience is that Jesus manifests Himself to Christians who obey Him. Christians who feel that they need to lie and scheme in order to advance in church authority sometimes find themselves serving in the flesh, because God will have nothing to do with their service. Christians who leave their religion behind them when they leave their homes often find themselves living powerless lives, because God does not want people to associate them with Him.
Do you want to be used by God? Then do it His way, not your way. Obey Him, and then trust Him to show you where to serve.
