2 Timothy 1.5 describes a sincere faith. There are those who claim to be Christians and then there are those with a sincere faith.
The difference between the talkers and the walkers of the faith is quite obvious.
Those who talk attend church but do little and give little toward the work of God which is the winning and discipling of the nations.
Those who work-out their faith live as Jesus did demonstrating a godly character while working at helping others see, experience and know God personally. Those with a sincere faith are attractive and cause people to want to become Christians.
Those who mainly talk about being a Christian without living a godly life are seen as religious hypocrites, often self-righteous, and no one to be emulated.
Those with a sincere faith seek to grow in their faith by reading the Scripture regularly, praying daily for more of God’s presence and to be more of God’s presence while helping meet the needs of people so that they too want to know Jesus as their Savior.
Having a sincere faith means focusing on the work of God which is the restoring of humanity to God through Jesus Christ.
A sincere faith is outward focused toward God and others, seeking the reconciliation of people to God; it is not self-seeking or defined by personal experience.
The Lord Jesus gave His life as a ransom for all and those with a sincere faith work in word and deed with God to rescue people from sin and death and restore them to life everlasting.
