Is it how much good you will do versus how much bad you will do? If this is what your faith is secured by, then you have already failed, for no man can be good enough to meet the perfect and righteous demands of God.
Is it how faithful you are to your church or religion? If this is what your faith is secured by, then your faith is in your religion and not God. A faith based on anything but God will fail because God will accept man on one basis only, faith based on the completed work of Jesus Christ which provides for our salvation.
Is it based on your performance of certain religious rituals? If this is what your faith is secured by, then your faith is based on the works of man, and nothing that man can do is sufficient to meet the demands of God.
For the true believer in Jesus Christ, our faith is based on the power, the complete sovereignty, and the grace of God.
38 For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
39 Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.
The closing verses of this magnificent chapter of comfort for the believer explores all of the possible ways that man can think of to try and mess up our salvation and separate us from the love of God. In our lesson today, Paul refutes each one of them and states that they are blocked by the grace of God.
Once you have made Jesus Christ your Lord, then nothing, absolutely nothing, can separate you from the love of God. Your faith secure because your faith is in God.
