If God has taken care of sin, sickness and death, the battle next is FAITH.
Faith is what we believe in, It is our believe in God. it produces tangible results but cannot be proven scientifically. Faith is not a result of logically calculated steps. Hebrew 11:1 gave a nice definition of it.
Paul’s advice to Timothy in 1 Timothy 6:12(Amp) says,
“fight the good fight of faith; lay hold of the eternal life to which you were summoned and (for which you confessed the good confession (of faith) before many witness”.
In life, this battle of faith is very vital, 2 Corinthians 5:7 prescribed that sight is not needed. It is a thing of the Spirit, manifesting to alter the natural rule or principle of sight. Sight came into being in Genesis 3:6. Prior to the act that led to the introduction of sin brought about the seeing eyes.
Faith is spiritual, it goes beyond what is seen naturally, The reason is because the natural sight has a way of limiting our possibility of attaining that which God has for us or which we demand by exposing and magnifying the negative things thus manifesting the obstacles.
Faith in the life of a Christian is essential because Hebrew 11:6 states “But without faith it is impossible to please Him; for he that cometh to God must believe that He is and is a rewarder of them that diligently seek Him”.
How do we receive this faith? In Romans 10:17 (Amp) says
“So faith comes by hearing (what is told), and what is heard comes by the preaching (of the message that comes from the lips) of Christ (the Messiah Himself)”.
Having received faith, it ought to be applicable in our daily living. James 2:7 says
“Even faith, if it had not works is dead, being alone”.
For us to live as overcomers that we are, we need Faith 1 John 5:4 says
“For whatsoever is born of God overcometh the world and this is the victory that overcometh the world even our faith”.
On the battlefield of life as Christians, 1 Thessalonians 5:8 says
“But let us who are of the day be sober, putting on the breastplate of faith and love and for an helmet, the hope of salvation”.
Concerning your health, James 5:14-15 says,
“Is any sick among you? …and the prayer of faith shall save the sick, and the Lord shall raise him up and if he has committed any sins, they shall be forgiven him”.
In conclusion, faith in the Lord is all encompassing to a Christian and all the Lord Jesus demands is faith as small as mustard seed that is what is sufficient to move any form/type of mountain in life.
